I have found Pyro to be a blast to play as a merc. It's so much more dynamic than Arsenal, especially in Voidstar and Civil War. I love dotting up anybody trying to attack doors and turrets. I've also found certain classes much easier to attack as well since they can't run from my dots and/or cleanse them. It does take a different mind set than Arsenal and it's better to use certain abilities in order and/or to proc other abilities. I usually do my abilities in this order (using Rapid Shots when needed to keep heat manageable): Incendiary Missile Thermal Detonator Rail Shot Unload (followed by Power Shot if it doesn't proc Rail Shot again) I also use Fusion missile on targets who are lower on health and in groups. I'd say keep at it and try different stuff. I've done both specs for many hours of pvp and Pyrotech is far from useless.

My group was doing this on normal and it was spawning insane amounts of Bounty Hunters. At one point we had 10 up at once. It seemed to focus on one of us and then spawn that individual a bunch over and over, within 1 sec intervals.

I have had a lot less fun since this change. I've enjoyed the PvP a lot more in this game than any other mmo I have played, but going from 5 min queue times to over 30-45 minutes has killed it for me, and I am now unsure if I will continue doing it as much as I have been. I'm down to maybe 1 game an hour instead of 3-5, that's a big difference since you can only do so much while waiting in a queue.
