You don’t understand how all of above average combined with all of below average is the entire set, by definition?
It shouldn’t be.
This makes you a glorified bugtester.
If masters and up wants a hero banned that’s extremely popular outside of masters/GM/OWL well too bad. You may have given them the money but you don’t matter.
You cannot support this then be surprised when the game is made objectively less enjoyable for you because you were outright told you don’t matter and instead of saying “no, we all matter” you said “yeah, screw me. Give the elites whatever they want, I’ll gladly take the scraps.”
EDIT: It’s just stupid to play around M/GM as we know that at that rank there are heroes who aren’t played at all due to fickle favouritism. How do you adjust for a hero who just has insignificant use?
