Is it me, or are the Warlock's starting grenades, compared to the Titan's and Hunter's, really sort of useless? whenever I toss one, I get a group of enemies in the radius for about one second before they all just scatter out of range, leaving the rest of the AOE to basically do nothing. Meanwhile the Titan's Gernade does significant damage and stuns everyone in the radius for a good amount of time, and the Hunters also does significant damage and comes with a DOT effect. I don't know, maybe I'm just not using them right, but I just don't see the Void grenades as that useful.
