i use tyreal for raiding, and was using it this morning, but i needed to drag my other healer through flex too.
so i pulled up my main druid on one monitor, and my disc priest on the other. used lazyraider on my priest, set my resto droo as the tank on lazyraider and we two healed flex1. my resto droo with tyreal and my priest with lazyraider.
edit, i might add, my droo is 565 and my priest is only 476
