I'm not an illusionist, but I was going to say about the same thing Kill...
If there's an illusionist available, I'm gonna snatch him/her up in a heartbeat. I'll kick a DPS, an extra healer, an extra tank, whatever...they're gone. "Hey...can you go find another group, there's a chanter available". Breeze + mez + silence = OMFG die zone!
