Lol, I think your overestimating the tactical prowess of some of our players. Some will have wirbs and osties along no doubt, but a good many will think that with the puffy AA, they have nothing to worry about.
And I place survivability very high on the list of importance. If it can be killed by an M8 at 2000yds, then, IMO, it doesn't need even a perk price of 10, maybe a base price of 4 or 5 at most.
