[quote]1) It's terrible in PvE, compared to other exotics overall. 2) In PvP, it's okay but not game breaking. Suros is a better overall gun for Crucible. Vex is terrible at range, and gives away where you are shooting from immediately. 3) Ammo. Vex holds only 163 rounds? Around that, that's including what's in your clip. You'll run out FAST. Not good for PvE once again. And also feels like juggler mod built into gun, rarely get ammo drops with it equipped. Switch to Special, and then you get ammo. Overall it's a fun weapon, if you're sick of the clack clack clack of Suros.[/quote] 1.) It's great in PvE for me. I can clear mobs, provided I crit hit many of them. 2.) In PvP it's great but I do find myself losing to the Suros or other rifles at times, due to the range of the mythoclast. 3.) I also find myself scavenging for ammo for PvE due to the lack of energy the mythoclast can carry. And I'm also left reloading a lot. Make sure to carry synthesis when using this gun in PvE.

You must not have a vex to think any other gun is better in most pve situations. You run out of ammo, it regens.
