As JSmith said, Barbie and Cyrus are more or less the same, but with different AW buffs. Mehlis still beats them both, and all of them lose to the plats (other than UP cost and odds of drawing, obviously).

Sasha is very good for murdering chokepoints. Extra AS on AW + highest raw damage, with a dodge skill for insurance is good stuff for keeping your heavy from being overrun

Edit: Wow, how'd I end up looking at (and thus responding to) page 5 from 2 days ago lol?
