Punishing players for playing the game is not an “easy solution”
GS is an easy baseline to form groups off of, even if you cheat 900gs with Ony neck it’s well enough up to Naxx if you know how to play. And if you don’t then more gs won’t help you.
You can get 850-900 with reals/bwl/aq10/Kara, and below 800 you shouldn’t try to get into aq20 hardmode runs.
