B2 garbage?

My fully upgraded lvl 80 gear 10 B2 (he cant be geared to 11 as of yet) has a total of 42k health/protection. Ive seen him crit at a max of 3.8k. Very useful against teams with RG/STH, makes their taunts completely useless. Yoda will never apply buffs to team and leia will be ripped out of stealth. Not sure how it is defensively, but if you are facing gear 8/9 B2 that means he hasnt got his extra 80% potency increase from scanners, therefore buff immunity probably wont stick that well yet. He attacks a lot but lots of damage variance with an average around 2.8k id guess.
