This is good though. It pushes Blizzard to create new 5 mans. They have been so lazy in this department. Tricking people to run the same 10 dungeons for 2-3 years isn’t great for a themepark MMO like WoW.
The level of toxicity that has come from M+ alone is worth looking into a better system to entice people into running them.
Your main character should have an end point. This entire idea of endless scaling just sucks for MMOs it is a lazy to keep players chasing that carrot.
