I'm finding video games have less and less appeal for me. Especially timesink ones. So I've stopped retiring in this game, having acquired a Divine Torch, and can play here and there without grinding through levels again. I've come to even hate the strat map because of tick grinding.
I haven't retired in over a year, but I respec whenever I hit 32 or 33 or something to a new, fun, high level build. I don't care about powerlevels, hate grinding, and enjoy variety (aka get bored as fuck instantly). Works for me!
