Mechagon Mythic Plus?

All you have to do is increase the health pool and modify the damage output which is what they’ll do with m+ and alter the timing of mechanics.

I still would like for them to just update the dungeon’s loot table for non mythic+ so there’s an option outside of mythic+ since every other “mythic” dungeon’s loot is trash and is completely face roll like LFR and normal/heroic EP

I mean sure, they could, but it would only hit the sweet spot of being challenging / rewarding for 1 narrow segment of the playerbase. For others it would be either too easy or too hard. M+ bypasses this issie by providing a scaling system that offers both replayability and progression for the ever evolving playerbase.
