The thing I hate about B/W more then ANYTHING is the female char design. Utterly disgusting and slutty, it's gonna be a pain looking at that the whole game, but I refuse to play as a boy given the choice. I also hate the lack of simple customization options. Like maybe 1-2 premade designs. I think they should have used the two rival kids as the main male and female design instead, or at least gave you the option of choosing them! Ugh. This is actually my biggest complaint about B/W.
My other complaint is the starters, yes. Mainly I'm sick of the grass type always being a reptile ever since R/S. I hate using grass types, they are one of the less useful types and there's no good grass attack moves for me personally. I loved Leaf Blade but it's now physical and useless on Sceptile -.-
But what I'm getting at is like, why couldn't they make a fire snake or something? Or even a water snake? Why must the fire types be based off stupid animals since R/S? First a chicken (though Blaziken is awesome) then a monkey, and now a pig -.-
However, if Mijumaru's final evo turns out to be true, I finally get to pick a non grass type! Yay! Though I may want Mamanbou as my water type, assuming it's not a Luvdisc evolution of course, which I am still confidant it's not, they game being a week away and still nothing said about it.
ANYWAYS...
Another thing I hate is Munna and Musharna being psychic dream eating tapirs, since Drowzee and Hypno already are.
Oh and hate the "monkey trio". Ugh. More stupid simians. As if there weren't enough already! Why couldn't they have made something like a trio of original monsters or mythological creatures? Like a Shishi trio or something (the chinese lion statues)
Other then that I guess I don't have anything to complain about really, unlike D/P, which I had nothing good to say about and totally skipped.
