The swarm grenade is nothing compared to the pulse grenade or Vortex Grenade. Both do AOE and DOT. Both capable of killing multiple enemies. The Swarm Grenade is for area control I get, but the damage is minute and might kill a single person. The Incendiary grenade is nice and does DOT but the DOT is again weak and doesn't last that long. The area of explosion is nice and helps bring people out of hiding. But, any grenade can do that. The Trip Mine Grenade looks sweet, but it all depends on the damage out put. If it can't kill someone, then what is the point? And, we don't know how long it will last either. Is it indefinite? Can you set up multiple grenades in an area? Can't say it is epic if we don't know what it does. Now, if it is like an IED and kills anyone to close, then sweet. If not, I think I will stick to Incendiary Grenade. I am more excited about the Blade Dancer though.
