I don't care what portion of the game is increased or decreased.
My point is you can't complain about easy buttons if you are not willing to have your portion of the game reduced.
As to epic XP, I have 3x completionist, so it wouldn't affect me.
I would argue that making XP/time easier as the game ages allows new players to catch up, and would be much better for the game.
So I would say your idea is really bad, even though it doesn't affect me.
