that i do agree with. the fact that raids are tuned around people being max ilvl due to the easy and quick acquisition of m+ mythic gear.
but i find that to be unhealthy and i know blizzard is really stuck in knowing what to do other than just leaving things as is.
before you get heroic dungeon gear, and raid. raids would get easier as each boss would get downed and players attained better and better gear. now the tuning is based on players being max to near max ilvl due to m+.
