but apparently Suros was KING of PVP before the auto rifle nerf. Got one from Xur a long time back, would be good to see how it performs when autos get buffed again.

Recommendation: Don't upgrade the first perk until you're deeper into the XP, at least up to the second big perk, where you start dealing bonus damage. The reduction in ADS fire rate isn't worth the slightly increased damage without the rest of the gun upgraded.
