Make it more like the Wizard's cloud, disabling anyone who touches it during the duration. I've made a titan, just for the "max a titan subclass" trophy, and I was severely disappointed in the grenades. Suppressor is cool on paper, but crap when put to use. The only thing I could see making it worthwhile is making a shutdown zone, the way there are DoT grenades that can be used to make a makeshift shield against melee attacks or be used to convince enemies to stay back out of a hallway. A shutdown zone could have the same effect in practice, the enemy knowing that going in would be a bad idea, and can be used to ground enemy players in PvP, allowing the defending player to freely fly and sprint to them, getting a kill off their grenade by suppressing the enemy. May sound a bit broken, but it's the third Defender grenade. I think it's worth it to have a zone of safety for allies, and a zone of suppression for enemies. It fits, and there are no defender perks toward the grenade that could break it by allowing it to do more than just shut down the enemy. Edit: Warlock -> Wizard, up in the first line
