We have done this a few times but yea, your dps has to be awesome because of the decreased damage toth takes. I find this method easyer if you have new/crappy healers but if you dont have the dps for it (alot) then you have to do it the old way. Both ways are hard, but this way is simple mechanics for good dps vs complex mechanics for run of the mil dps.
It's funny how you say "others can now use this to cheese their way to victory" but really, dps is tight, give it a try and see how easy it is lol. I have a hard time breaking 1650dps using this method, where as normally 1750 is usually par for the course.
My thoughts exactly. Both strats are viable. Both capitalize on different strengths of the group you bring in. Thanks for your input.
