I hope future HC seasons go back to the previous grouping format, at least in epics. Having a 2 level over quest lockout is awful for epic grouping. You can spend (literal) hours waiting for a group. Yes, there is attrition that lessons the population in epics but the highly restrictive 2-level limit makes getting going painfully arduous. I hope this doesn't return in the future and is marked down as an experiment that didn't have good results for group play.
