Backpedalling a little here, has anyone struck upon anything that could be labeled an adequate control power, just to help those in the game not as comfortable with the "smash smash smash KillItNowKillItNowKillItNOW OrWe'reAllGonnaDIE" approach that CO seems to engender? So far I've found:
Celestial's Vengeance (aka Holy Orbital Death Ray), with the Redemption Denied advantage. Two second charge to hold the target and stun all his friends.
Darkness's Grasping Shadows (aka Not-So-Tenebrious-Tentacles). Again a two second charge, but with an AOE hold.
Anything with consistent Knock-Up/Down/Back. Foes on their backsides aren't hurting you. For some reason, Knock-Toward doesn't seem to make enemies fall over as much. *grumble*
Seriously, a two second charge on a 10-15 second hold makes such a power pretty marginal, IMHO. And I'd maim for an AOE Root power, just to get minions to stop scampering around.
