I am against.
One more powerfull weapon will destroy variety of usable PvP builds and weapons in Hinkley
Now you can use P90, 223 pistol, Sniper rifle, R, minugunL, Laser rifle, Plasma r., plasma nades, Supersledge..
If you will introduce another more powerfull BG, you can erase half of previously named weapons. => PvP in Hinkley will not be about how you can use your weapons (player skill), but about more AP build.
Also, i dont think that BG are bad there.. They have good RL = kind of sniper class with constant damage. Sniper (SG) cant use their weapon in the interiors and if they camp outside building, you can always go with your minigun/RL covered by walls to enough distance to burst or at least fire rocket to enemy => you need more tactics.
Anyway, if one team is made by BG only and one from sniper only, BG has biiger potentioal to win (stonewall perk = ability to rush even in open space). So, please, dont add more powerfull weapons into the Hinkley.
Players could always take their avengers and kill leather jacket Modoc militia, if they suffer that somebody else are killing them.
