Crowd Control's never been much of a requirement in Champions Online, but with the recent Save the Earth alert's design it looks like some mass CC would be very helpful. I've had a few toons with low-level or single-target CC powers, but I've never focused on CC on a character before. So the question is: what's the best power &/or power set for locking down enemy mobs en-mass? Is there anything that could lock down all the spawns in Save the Earth, to let the rest of the team get to work? Or would a decent CC build be only a partial 'solution' to the alert's design? Or not helpful at all?
If there's any existing threads covering this, feel free to point me in the right direction!
Thanks in advance!
