Wheel of Destiny At HT or any boss

Well last night I was HTing on a Bishop and I became seduced at right arm and died. I had a Wheel and decided this would be a good time to try it out. Wham, came back instant death, even with a bishop healing me, due to the lag upon reentering and no MG even though I was spamming MG . I am not sure how this will help at PB battles for Mage classes. I used a Wheel on my Hero and experienced major lag upon reentering also but atleast made it through. I was curious if any Mage class had been Succeful in using a Wheel at a Boss and survived after using it.
