Unless they made MI not be on the GCD for us, it would almost certainly be a DPS loss to use them. When I tested them on beta their damage was pathetic.
Only ones I could see myself actually getting would be the defensive CDs(AMS, Unending Resolve etc), because the rest are just awful. I can't see MD being useful, because we don't have the easily useable burst AoE hunters have(2x Multishot, 1x Cobra/Steady, 1x Multishot).
I can't actually remember the rest, because none of them are very interesting.
Would be lovely if we got Spiritwalker's Grace, Leap of Faith, Demonic Portal(yes, I'm jealous of the resto ones)
