To me a lot of what expendable wants to do is pretty radical, I mean I could see a lot of it making sense but why not make suggestions relative to the current list instead of trying to remake a new one. As for blissey being worst than chansey I agree it is but I dont think its like the worst thing ever and belongs in C tier, id say its one rank lower its not like you should laugh at someone for using it over chansey its a bit less risky and can kill gengar which is a nice plus. Although if you play blissey I really think it should be calm. As for Latias I dont think its so bad ive seen some people laugh at it but if latios is A+ then it should be A in my eyes, since its stats are so similar, its a waaay better defogger, has a destructive calm mind set, and its like a top 3 pokemon in the UU format on showdown too, which should be an eye opener for people underrating this pokemon. I mean things being slightly worst shouldnt make them drop all the way to the bottom of the list its not a night and day type of difference.
Theres plenty of things I disagree with on the list for sure, but I dont list them all out and try to change the whole list to be as my opinion I just choose the most critical one in my eyes. Of course everything im saying is just my opinion and I could easily be wrong. We are all just trying to improve the list but I think its best to take small steps at a time rather than 15 at a time. Since I dont want to be looked at as if im picking on expendable (we all appreciate your opinion ) Ill point out what I liked the most out of all your changes. To me you hit it right on the bulls-eye with donphan its just not any good anymore relative to all the new defoggers we got, I couldn't agree more with what you said on this pokemon.
Heres my suggestion:
Dragonite: from A to A+:
I think the unpredictability of his movepool should make this guy A+ having access to so much coverage moves and multi scale should make him a pokemon everyone considers to having an answer for on their team. Assuming their answer is weak to his coverage it could mean nothing as well so it can be a definitely a guessing game for the opponent.
