Okay, so I've tried using messenger, fulcrum, vex, and many other weapons in crucible. But every Damn time I kill someone, I'm poisoned to death. My solution? I've started using thorn. It wrecks. And it's very much overpowered. But now, I use it and live for gunning someone else with thorn down. Haha. That's what it feels like asshole. But yeah, IB sucks because of thorn, trials sucks because of thorn, and crucible in general sucks thanks to thorn. So I think I'll just keep using thorn till they nerf it into oblivion. Haha, but seriously, I inly use thorn now to -blam!- with other thorners. Sorry if you get caught in the cross fire. Edit: I put down the thorn for now. Don't want to be that guy on my team. So now I've been using messenger and the fulcrum depending on the map. Both of these guns are awesome for crucible.
