Low AA Bonus XP to Increase in June

Currently, if you have under 2500 AA, you get bonus AA XP.   The bonus degrades linearly from 500% [normal xp times 5] at 0 AAs, to 100% [normal xp] at 2500 AAs.

OK. So I'm taking the bonus to 4000AA, with a 1000% bonus degrading linearly to normal XP at the 4000 mark.

June patch.
