This is just sad to read.Ame made a free game and even though you feel it could be better thisamount of critics, just no.
I think getting these pokemon out or introduce them later is fine. There are plenty of pokemon you can use and for the sake of diversity it is only better to remove the most popular strong pokemons. I, for example, am playing with a lot of pokemon I never considered before because of my preference for the better popular onces. but guess what they turn out wondreful and I am happy Ame removed osme of the popular ones.
as for the older players better pokemon. that sound a bit like a butthurt fan that wanted that pokemon for themselves. when gettting new levels some pokemon might get other purposes and get changes, deal with it not really some point of contention.
please dont make things easier, I love the difficulty in puzzles, it makes it much more rewarding when you finish them (even though the chess one wasnt that hard). the part i love most about reborn is the differences from other pokemons, it is not a 8 hour 2 pokemon needed game.
