This is precisely why Blizzard curtails grind-behavior. You addicted apes don’t know anything else besides over consumption, as if this game is an opiod or candied delicacy that you need every last drop of (which is so ironic because of all the incessant hate that gets spewed about the game, yet the worst offenders continue to play it).
The cap doesn’t make you do anything. You fuel your own sense of FOMO. If Blizzard didn’t put a limit on things you min/max monkeys would play this game to death and then have the audacity to scream that the content is dry and there’s nothing left to do.
No one is forcing you to do anything. You can still push rating without running 15+ mythics, JFC. The culture that is “created” as a result of caps is a hell of a lot better and more sustainable than the culture that would exist without the caps.
