I've had an Illusion/Cold controller for ages, as a replacement for one of my first characters on live, Illusion/FF. After hitting 50(+3) and shelving the character for a year to pursue other interesting characters, I'm ready to revisit and actually put some sets to use. There are several threads talking about how great this combo is for killing AVs, but I'm more looking for the ability to lead a team, small or large, through high difficulty missions without risking much death. Here's a build I've thrown together, but I'd love some input as to how to make it more soloable, or conversely, how to maintain softcapped defense while maximizing recharge.
