Just curious...why is the post called Rays of Distortion?
I hit a macro warning the group. Also, lock asked me to add a tell to it (which unfortunately he get's all the time raiding or not lol). Cast a couple of spells and hit Rays. I only use it on the longer fights when it would matter more.
I really don't see why some compain about it. Yes it interrupts, but if you have a 5 sec warning it's easy to manage and pushes up the DPS.
