Got to 40 and ran more PvP today. Pyro is a TON of fun. I'm consistently top 3 damage in warzones, and by using Rapid Shots I'm very mobile. I barely use Power Shots, to the point I'm considering taking it off my bar. I think in 4 or 5 warzones I used it maybe 3 times. Waiting for Unload to proc PPA and setting up for burst just seems a lot easier and fluidthan tying to proc PPA as often as possible. Would I do more damage? Probably. I probably should use PS more often than I am, but I find by the time I get my CGC up from Rapid Shots it's time to do my burst rotation again.
Glad you enjoy it like I do.
