Dont care on the matter
Agree with many others, MI had a good flavor but never felt it had the matching impact in PVE, would be happy to see it becomes a real potent CD even if it means it's becoming a talent
Of course, 90% is too high as this would be only the "15% average benefit" for n*3min fights... so maybe it's just 60% additional damage or so... isn't that a bit "bursty" (concerning PvP) ?
Well, I do not play PvP at all so maybe I can't evaluate this, just something that came to my mind.
@Poll: I like the fact that MI will be buffed to satisfy the role of a damage CD (now they only deal a very tiny percentage of your total damage), but I don't like the idea of converting a baseline spell into a talent
