I'm hoping it won't make much of a difference in PVE stuff as it was already kinda crap there, due the pathetic amount of ammo you can carry for it. I unlocked the upgraded battery which gives it 56 rounds per magazine, you can burn through that so fast!
For PVP, I'm glad I got to use it and will try get a few more games in before the damage reduction, I managed a 7.something KD yesterday and you know where I usually sit in the scoreboard haha. Still think it's rather steep though!
I'd like to see different stats implemented for crucible and PVE stuff ideally!
I guess it's a fair amount of work to hold 2 sets of stats for weapons though.

It's always the same with these balance patches!
