Thanks!! I"ll give it a try

I used a ping pong archer xD. I just didn't wanna jump on the bleeding edge train :(

Funny name. I also have a ping pong archer. Gonna call it that from now on :D

I had no problem with Lambach, really. Compared to Edric's whirlwind spam the act 2 boss was a walk in the park (run to the circle, sidestep the tentacle things during immune phase, ect).

OFC, it took 4 respecs to find something that could deal with Edric - that being poison/burn DoT (Pistol/Catalyst). That setup burned down Lambach pretty handily as well. 100% wisdom build.
Primary skill was burning embers and anomaly, with havoc orb to burn off rage. The adds died so fast they were a non issue entirely. That entire fight was down to dodging - but, unlike Edric, you had time to recover before the next phase.
