best use of mutant bio pack. weapon x or gambit?
Gambit is much better at WBU, which can drop premium items. Go Gambit.
Weapon Hex is way better than Gambit in AC. Gambit hits like a freight train but has the survivability of a fly, I have both at T2 and I think WH is probably the best character you can get in the 20 x-gene sub since she's useful in both PVP and PVE
