These games are almost always fun to just level in, get all the pieces you need for your build, go wreck some shit for a few days and then quit. Grinding paragon, perfect rolls, pit levels, maps etc is just boring. At most you maybe try another build or class, but after that just wait for another season. I usually get at most 2 weeks out of playing before it turns into a pointless grind.
More power to the people that can sit in these games full time for months and play. Really getting your money's worth.
