I have three her mercy with the following rolls I don't know which is my fav yet though. Sureshot Zen moment Extended mag Outlaw Sureshot Zen moment Explosive rounds/braced frame Spray and play Sureshot Luck in the chamber Braced frame Final round I think I would prefer the final roll on a fulcrum as it'll only have 6 rounds not 8 so a higher chance to proc. So far my fav roll is the middle one with either explosive for hordes and braced for higher tier mobs.

Got final round, braced frame and luck in the chamber on my and is ascended will be using on pvp :D

I got one with final round and luck in the chamber which is a bit ridiculous.
