Yes, nerf the vortex grenade
No, it's fine the way it is
What does the community think? What I have found so far is that Warlocks don't think it should be nerfed while the other classes do. I'm a hunter so this may seem biased but I think the grenade should be nerfed cause it is much better than the titan grenades and the hunter grenades. Post your own thoughts and also what class you are so we can try to see a pattern.
