I think M+ Rewards are far too generous, and do not reflect the level of content completed
A person can do 5, M+5 dungeons and have 2, 210 item slots in their guild vaults.... this seems like charity, it does not seem reflective of the content
Today's M5 dungeons are not much harder than normal WoD heroics. Some of the extra mechanics such as beam soaks, and add interrupts and cc's were simply standard practice in normal heroics in past xpacs
I feel that the easy gear in M+ has ruined wow's entire gearing system, where no one enjoys what they are doing... they just gravitate to the easiest source of gear
