but you shouldnt expect there any as there are other reason to raid... right?
gear from raid is less scarce, and at least difficulty level appropriate, M+ (except weekly chest that is SHARED with raid and pvp) not so much...
so runing M+ for less AND worse loot than raid should be fine as there are are other reasons to run it, not just "loot pinata", but from raid you should get all that AND good gear AND option in vault?
seems a bit... unequal
and sure, you can run m+ more, but if your goal is loot there is no point you can do thousand m+15 and the little gear you actualy get will still be worse than hc raid...
