I realize I haven’t updated for a couple of weeks.
Dinged 40 on Chillhunter. Tried Advanced Prototype and several hybrids. The damage was less, and significantly less bursty. The additional utility was not really noticeable. So I am back to my pyro spec.
Also, I tried pyro’s 31-point talent, thermal detonator. It was ok, but not really worth going out of my way for. Looks like I am going 8-6-27.
