M+ in Bfa had the main issue of transforming from “alternative” gearing path to “main gearing path”. Raiders, PvP guys and etc. All were forced to spam M+s like there was no tomorrow to be viable in their own fields(raids or pvp). While I am a m+ runner myself. I understood that it caused the issue of m+ becoming the defacto main gearing path. While raids, rPvP just became “something to do when you are bored from m+” pretty much. And for those who went for high ratings or mythic raids, they pretty much HAD to spam m+s just to be viable.
Blizzard adressed the issue and M+ are no longer a loot pinata as it was before.
M+ rewards less loot but remember that it can be spammed to infinity. While raids = clear it once. Bad luck? Though. Better luck next time.
“Increase the rewards to make it worth it?” Its a very veeery slippery slope there. The line between “alternative gearing path” and becoming the “main gearing path again” is extremely blurry and thin. Since M+s can be spammed to infinity, it HAS to have a drawback to compensate vs raids who can be done once and only once per week.
