This is my feedback from playing a mercenary bounty hunter, I LOVED the bounty hunter storyline from start to finish.
However, both arsenal and pyro merc sucks HORIBBLY in pvp, they are terribad against melee classes. No interrupt (not stun) , very low survival in pvp, melee classes eat you alive in a couple of secs, mostly sentinels and guardians . . .
Think im gonna reroll a powertech I hope to Christ they are better in pvp that the lolmerc .
