Well being I asked the questions, I might as well answer them myself:
TYPES:
(1.) Of course I think there should be a Dark-type, we so far had two Steel-type Gym Leaders and a Champion. And though we had two Dark-type Elite Four Members, I think it's about time there was a Dark-type Gym Leader.
(2.) Of course, I mean we had plenty of Rock-, Electric-, Water-, and Fighting-type Gyms, give types like Bug-, Dragon-, Ground-, and of course Dark-type a fair turn.
(3.) While I wouldn't go that far as to completely agree (kind of odd for the person who wrote the question to say), types like Rock-, Water-, Electric-, and Fighting-types have been in most of the regions so far, often back-to-back(-to-back) Generations. At least they try something new like having a Water-type and Electric-type be the eighth Gym Leader, but of course then we have the Rock-type Gym Leaders who have always been the first Gym except for Johto.
(4.) Yay, I mean I understand if you want to make it tougher for one starter then the other, but having the Rock-type Gym Leader being the first always means Water- & Grass-types will never have to worry while Fire-types will have to hope thye learn a Fighting- or Steel-type move to even get past (that or the trainer catches another Pokemon with a type adventage which many don't want to do for the first Gym).
(5.) Now my problem here isn't with that they use these older Generation Pokemon, but it's the fact that they use more older Generation Pokemon then the one from their Generation. Now for those specific types this can't be helped, but I do see some other Pokemon from that Generation they could have used instead (They could have atleast given Morty the only new Ghost-type introduced in Generation II!).
(6.) Not sure on this one. Now while it does seem so for the first game, for the later games it doesn't seem they are basing on the type of starter which determines what type the Gym Leaders are. I don't know how they choose which type will get a Gym Leader and how they are organized, but as for the theory of it being the type of the starter that does it I don't think so.
(7.) Now I think what they should do is keep 4 types from the previous Generation & then used 4 types that weren't chosen. Infact this is what they seem to have done in Generation IV, though that could be just coincidence (Generation III only had three types that were also in Johto). So with that in mind and I'm in support for the types not so often see I'll go with the following types (though in no specific order): Dark, Ground, Bug, Poison, Grass, Ghost, Steel, & Ice. But this is just coming from the top of my head.
(Extra.) Can't believe I forgot to add this in, I also would like to see another Double Battle Gym. I mean so far we only have the Mossdeep Gym Leaders, Tate & Liza, as the only Double Battle Gym Leaders.
PUZZLES:
(1.) I would prefer if all the Gyms had puzzles, though the first Gym's puzzle should be easy and have an alternate way of getting through it (a.k.a. battling a trainer).
(2.) Gah, I hate those kind of puzzles, especially when you get far into the gym but you go one wrong direction and you either end up back at the start of you messed up and have to first navigate your way back to the start to do it again.
(3.) My favorite Gym Puzzle would have to go to Sunyshore Gym, I'm just really impressed by it. As for least favorite, Mossdeep Gym in Ruby & Sapphire as not only is it a sliding puzzle but you also have to flip switches to hopefully create the right path!
(4.) Hmm, well what I think would be interesting is that maybe changing the Gym's Leader position so that it's the opposite of what it was in the paired games would make the game rather interesting. What do I mean? Well I mean like switching the positions of the 1st and 8th Gym Leader, the 2nd and 7th Gym Leader, the 3rd and 6th Gym Leader, and the 4th and 5th Gym Leader. That should make things rather interesting and thus also change up possibly all the puzzles as well!
(5.) This was only done in Generation II, first sorta with Whitney but you just had to talk with her again, and then lastly with Clair with going through the Dragon's Den. I don't think you should have to go through a second puzzle, no need really.
(6.) Hmm, I don't quite exaclty know. I'm thinking about maybe a puzzle where you have to create your own platforms to get across but I wouldn't know how to go about that (plus a few Gyms already sort of do this).
BADGES:
(1.) I would like to see more complex Badges, at least in design if not in shape, as they are must more interesting to look at and somehow feel more worth it then simple looking badges.
(2.) I actually prefer Badges which represents the Gym Leader/Gym's City/Town rather then the type of Gym. It gives the Gym more freedom and an extra plus if they can make the Badge both represent the type of the Gym and the Gym Leader/Gym's city/town.
(3.) Individually named seem to be working just fine. Theme naming doesn't always work and gave the Japanese Kanto Badges quite the bland names.
(4.) Yay, I think they should have, but what can you do?
(5.) I never really noticed any drastic increase in the stats so I would say only include it if the change would really make the difference. I might change the order of which stat the Badge increases depending on what Gym type it is. Finally I think that the Special stats should be split up only because I think the last Badge should give you ALL the bonuses (HM, Level, & Stat increase).
(6.) I levels seem fine by me, though go increase by 30 (30), then 20 (50), again 20 (70), and finally 30 (100). If I was doing it, I would have gone more for an equal 25 increase for all of them making it a 25, 50, 75, 100.
(7.) Sinnoh's design has a nice look to them and I lik how they used the Badge's border for more than just to go around the badge.
GYM LEADER MODELS:
(1.) I rather they go by type. I know the plant naming thing has to do with Japanese culture but if it isn't a Grass-type or Poison-type Gym Leader (if the plant they are named after is poisonous) I don't think it quite fits.
(2.) That seems a bit limiting, I mean the other types don't seem to have a theme to their Gym Leaders, plus I don't exactly think military when I think Electric-types.
(3.) I wouldn't mind more diverse names. Like instead of "Rock" they can come up with a name that's based on "gem", "fossil", or a specific kind of rock.
(4.) I would like to have the Gym's Leader theme better known as the Gym Leader should be a person who is known for meaning something and having the Gym Leader be like an average Joe/Jane kind of takes that atmosphere away.
(5.) Don't really care eitherway, though I would rather for thier to be a good storyline reason.
(6.) I wouldn't mind seeing a Gym Leader based off a Firefighter, police officer, and doctor. I mean when you think people you should admire at least one of these guys might pop up in your head so why not make them into a Gym Leader.
Also, guys, Elite Four & Champions are next, so you should really be saving your types for Elite Four & Champion for the next post.
