To those who've quit: What would make you come back?

I know nothing about the game, but I bet it's the kind of game that's overhyped and will be forgotten in 5-6months.

Or will at least only take a small fraction of the users who have "quit" with the release of d3. LoL was apparently a hellhole on Monday. People were trolling because they "didn't care" about bans. They always come back.
