It's not a deal breaker but if x weapon comes with the same perk rolls and you get like 50 them where is the fun in that. Or you find that one gun you think if I had this with z perk it would be a beast. It just removes the fun excitement of getting x weapon to see what rolls it has. And as much as people gave out about the grind it's what they all loved whether they new it or not. Because that's all this game has been until 7/8 month's ago was a grind fest and we are still here. Just think all the hc pr sc bounties done the last few weeks with people looking for God rolled whatever. Or all the poe coe archons forge done for the exact same reason. Whether knowingly or not bungie just reduced the playing time of players massively.
