After trolling for months, I guess I will put my two cents in.
The base stat changes seem like an interesting theory, though I'm going to hold off on believing it until I see it. Though, if real, I see how it could mess up transfers of old Pokemon. However, as long as they kept the flavor of the Pokemon intact, then all the work on training it properly should be okay. (Such as keeping attackers attackers, defenders defenders and so forth). I can't see them doing anything drastic like turning Hitmonchan into a Special Attacker or Jynx into a physical attacker (I know those are obvious, but I'm just using them as examples), so investments still might be fairly intact.
Speaking of Jynx, new evolutions for her, Tauros, and Khangaskhan are also iffy in my book. I thought it was confirmed 149 all new Pokemon (pre-National)... so for these people to find them, they would have had to beaten the game, transferred in said Pokemon, and just happen to figure out how they evolved?? I guess, hacking is an option as well. Although, rumors of a Tauros evolution go WAY back, and I also vaguely remember the creator supposedly saying that evolution lines of previous lines would be finished. So maybe it is 149 new in game + x amount of new post national. That's a lot of new Pokemon. I can't picture a Jynx evo in my mind though... She's already an adult looked Humanshape female. I can't see her losing her Humanshape form, also. Maybe unless she looks old, but that would probably kill her speed, which would render her even more useless.
And for the new cat: A "No Luck" ability would be cool. Nullifies any chance of a secondary effect happening against you by the opponent (unless it happens 100% of the time). So basically, no flinch-hax by the likes of Jirachi used against you. As well as Thunder now has a 0% chance to paralyze. It would be an F.U. to people looking to abuse the new Rainbow thingy. ("What does this mean?"). Could be cool and give it it's own little niche.
Things I would like to see/would be interesting to see:
I always thought Pursuit (albeit pretty balanced already) should or could fail if the person fleeing is faster than the pursuiter. If speed stat is really reaction stat, it makes sense, because the pursuiter didn't react fast enough.
Everyone says Poison needs a boost offensively, but I really don't want to see them mess around with the type chart. (I already have a hard enough time remembering it all). Therefore, it would be interesting if say poison type attacks do 1.5x - 2x more damage on Pokemon that have been poisoned. Good poison type attacks aren't thrown around that much (I don't believe) other than toxic, so only real poison types I think would be able to take advantage of this. 2x more might be broken taking STAB into account, but it might give it an offensive boost a little, while making sense.
I suppose that could go with fire hurting burned Pokemon and electric hurting paralyzed pokemon more, but I wouldn't be for those at all. I think their secondary effects are good enough. Though ice hurting frozen Pokemon more is a possibility.
Hail, I think, will get a boost, just because of the boosts that Sandstorm got last gen. I'm thinking it will be defense if anything.
And I hope float is false. I don't want another water HM. Surf/Waterfall/Dive drove me crazy in RSE.
Finally, people complain because of rehashing of ideas this gen. Well, with no old Pokemon pre-National dex, there are a lot of roles to be filled. We of course will need the standards met for beginning routes, caves, water, etc. Not every Pokemon can be or will be badass/competitively viable, as awesome as it would be if they all were. I do agree that the ones shown to us have been more on what appear to be "cutesy/novelty" (Tabunne looks like it will be the Skitty of this gen), I think they have kept the huge powerhouses hidden for us to enjoy. I'd rather be surprised by something badass, rather than Emonga (which I must have regardless of it evolves).
And I'm not even commenting on starter evos. I have a headache just thinking of the arguments I read. (Though, I will say, that Wotter will most likely be my starter)
Sorry for the length, but there's been a lot of discussion I have been thinking about and this is my first post.
-Cheers.
