You do fine in the crucible because the suros is not the best gun in the crucible. It's a great weapon in pve, dominates for sure. It's decent in pvp, many other auto rifles deal more damage than it though. It does indeed have minimal recoil which does make it pretty much the best AR for longer engagements, but you can easily just avoid those situations. I have a suros, since the first time xur sold it. I use it now and then in the crucible, but I prefer my grim citizen 3 as I can win more battles with it and use it almost all of the time. So none of your multiple choice answers actually do any justice to the is topic. I have suros, choose not to use it in the crucible because... because I do better with legendary auto rifles. I have heard of people who do not upgrade it to have the slow fire rate, claiming it performs much better this way in the crucible. I almost bought another one to test that theory but decided against it, deciding it would be too weak with just barrel attachments. But who knows.
