Not complaining about the class, but 3k crits are laugahbly easy. Heck, watch this fresh 50 guy with 0 expertise get 2500+ crits with Grav round. (post 1.1)
I saw a video of a battlemaster geared Commando Healer getting 3500+ Charged Bolt crits, he even got a 4400 one at some point in the video. (Post 1.1 btw)
