people STILL dont understand that its very much expected that people resub for new patches and unsub as soon as they get bored. thats expected by blizz.
they tuned their game to a "seasonal releasce cycle", with major expansion releases in between.
i mean, the pvp and mythic resets are already called "seasons". so, if 8.3 starts to bore you, unsub and enjoy the shitload of other good games that are currently available.
