I only have 2 exotic primaries. Mythoclast and Suros. I only have 2 legendary primary, a scout rifle and pulse rifle. Suros is much better than any of my weapons. Hopefully I'll get some more stuff soon now that I'm raiding and doing nightfall. I don't do crucible very much. Simple fact is that I suck at it. Doesn't matter what I use I just suck at pvp. As far as PVE goes though Suros is a great weapon when fully upgraded.
