I want more variety. So far, we have too many humans, elves, half elves. I want gnomes, halflings, dwarves, dragonborn.
I really wasn't happy about two slots going to companions, we already had in two games. I never liked Minsc and I don't know what more there is about to learn from Jaheira.
I really hope, we don't get more recycled characters.
And I don't want to loose the companions, not currently in the party, after act 1. That is a really stupid mechanic.
So all in all more race variety, especially short races, less recycled characters and I don't want to loose them after act 1.
Oh and another rogue would be nice, so I can ignore Astarion.
