I'm totally over MOBAs after realizing that the time sink and number crunching homework was really stupid. Doesn't help that winning is not rewarding, and losing is frustrating...I play 20 games just for the chance to play 1 game that doesn't end with me rolling me eyes because partner A sucked or enemy B gave the game away. And, when you finally find a decent game, the game's wheel in the mud gameplay shows its ugly head.
Then there's the balance nonsense and the constant patches that change balance...more homework. More time commitment.
Mobas are one of those things, like most games these days, that require a high dose of OCD to make it even bareable or even something remotely defined as "fun."
