I only got Average but i'm thinking they're gonna want some people new to MMO's, to check out how they experience the game, plus, I don't think that the score you get (Average, Above Average, Excellent) actually holds THAT much liberty over whether you get picked or not, i think it separates people into three groups, and an equal amount will be chosen from each to test the Beta... think about it, if filling in the guild slots gets you to excellent, why would ZOS want EVERYONE in the Beta to be part of a guild? That's just not diversity and its not effective for them..
Could be totally wrong, but you know, clutching to straws >??
