Wait, wait, what? What's the big deal about a dark type gym again? There's a dark type Elite 4 member already anyways.
Meh, let me go down the list...
Pokemon following you around like in Yellow,HG,SS - Sure, why not?
Berry Trees Back - Don't really care for them. Didn't vote. Wouldn't be against it, just don't exactly want it.
New Battle system (6 on 6, etc.) - 3 on 3 is already half your highest possible team size, no.
Multiple Regions - Past regions incorporated into the game, yes, two separate new regions, no. I'd rather they concentrate on one.
Battle Frontier return - Never experienced the battle frontier, didn't vote.
New Starter types - Nope. Fire/Water/Grass is fine as is.
Dark type Gym Leader - No...Errm, don't see what's the big deal about this one that it had to be in the poll to begin with.
Tournament instead of elite four - No, the Elite 4 are just fine.
Return of team rocket - Not as a main villain group for a game, but maybe some side story events with them? I don't know. Didn't vote for.
New Eeveelutions - Didn't vote because I'm indifferent towards it, but I wouldn't be against any new Eeveelutions.
New storyline(Not the old ten year old sets out to be champ and stop bad guys) - Voted for. A new storyline in a main game could be nice.
