First off, wasn't saying that ALL the ideas being suggested were Farfetch'd (heh). I didn't name names because I didn't want to ruffle any feathers, but it seems now that I was too general.
I do get a bit annoyed when people get into the real specifics and start suggesting base stats for evolutions and stuff, since that sort of fantasizing is generally kept off the forums in general (primarily to keep the forum from being cluttered by "what if"'s). I think that the mods decide to just let it slide in new game threads since trying to trim all the fantasizing would be impossible. In any case it doesn't really do any harm here, at least not in the absence of any real news. It's just hard to suppress that gut response. Still, that wasn't the main point of the post.
The main point wasn't so much at the little things that could be added (the location based field effects being a good example), so much as at the suggestions that key cornerstones of the game-play be thrown out, reworked or completely replaced. It actually had relatively little to do with your post, Bashfrog, except for the bit about training Pokemon to gain resistances to types, since that'd really screw both with training by making it more complex and with battling by adding new uncertainties with regards to typing, further complicating matters. Still, that's much more reasonable than some of the OTHER things I've seen suggested, like the abolishment of IVs and EVs or that "attack speed" suggestion. Independent of whether those are good ideas or not, they'd never happen because they'd change the game mechanics at their core.
Really this is most evident because of Generation V, the first generation to not have any major mechanics tweaks. It's pretty apparent that Gamefreak is happy with the way everything is calculated at this point, and that they're expanding in different areas outside of core mechanics instead at this time. I just don't see Gamefreak taking any huge leaps and changing battle mechanics up in that way anymore. It simply doesn't make sense that they'd rock the boat when what they have right now works so damn well.
I guess I just want people to be a bit more realistic in their predictions and guesses. Fantasizing is fun and all, but I guess I'm really looking for meaningful discussion on what might REALLY be in the game, instead of a bunch of wishes and role-playing.
Then again, I suppose all the information we do have has been discussed to death so we don't have much else to do but fantasize, so maybe I'm just being a stick in the mud :P.
EDIT: Oh, and to clarify, I'm not suggesting that these sort of changes would necessarily ruin the game, only that they're too big a risk financially for Gamefreak to try. Any fandom can be really dumb at times, and if something changes in their favorite game, even if it could be interpreted as for the better, a lot of people will denounce the game as being an insult to the series or whatever. They still might buy the games, but Pokemon isn't a 1 game deal; it's a series that's going to run indefinitely. And those people might not buy Generation 7 if they didn't like Generation 6. Gamefreak and Nintendo can't risk putting off their core fanbase like that, as it could have disastrous long term consequences.
