Can you actually fix this massive client crash issue? Close the game for a week or something but fix it.
So maybe I'm just a bit ignorant, but what difference in result is there between closing the game for a week to do fixes vs just repeatedly doing unscheduled maintenance?
If there's no difference, you can just take your week off the game and let the rest of us try logging in and play for whatever short periods we can instead of closing off the game completely from everyone.
