To be fair, the majority of the game hasn't been tested. That wasn't REALLY the purpose of EA. So that seems a bit of an odd argument to make to me, when, what, 80% of the game was still locked away?
Changes to the ruleset and racial attributes don't exactly require the entire game be playable in order to have a meaningful opinion on them, especially since one of them is literally about character creation, the 1st thing you do in the game.
Tbf a lot of balance will depend on how good the race bonuses are on late game weapons.
