Well, I'm in the process of giving up bh to build up other trees. I enjoyed the specials I had as a master bh, but I still died a lot. They drain a lot of your action pool. I didn't use the fast blast much, but other people seem to swear by it. I used spray shot a lot. That shot mixed with the pistol torso shot and bleed seemed to take down mobs pretty quickly. LLC Cone 2 I only used infrequently in times of massive agro, and I would say it only helped about half the time. I don't know if Master is worth it. I enjoyed it while I had it, but felt a need to go try something else after a while. I guess I would just state that spray shot was probably my favorite. Hope this helps.
