I never was a big advocate of the WW, but it's cool that we are getting it.
I'd be very doubtful if it had 2.2k ranges. I wouldn't get your hopes up THAT high.
Also, that's a good point about the ammo drums. It'd be sweet to have to TIME your attacks (and not waste rounds in between bursts) for when a target is dead to rights.
Without ammo reload delays (short ones) I can imagine this might get a perk. Spitting out a solid wall of 3200 20mm shells without pause isn't very balanced.
With a short pause built in (can HTC even do that??) it would add a bit of balance. 2 working in tandem could cover each other during reloads, etc.
Yeah, I know, not going to happen, but it would have added a bit of depth to their use.
