Just a heads up for anyone new to HC, there's a hard lockout once you take level 20 preventing you from doing heroic level quests. The faq only mentions a base+4 lockout and zero mention of this hard lock; so if you're doing favor don't make the mistake of taking 20 before you're done with heroic quests.
There is a level lockout to prevent characters from running quests too far over level. (Base level +2 normally for Hardcore, +4 this season.)
The 9th Season brings a return of the third season of the Hardcore League called Saving Grace. This season features a +4 level lockout in addition to the ability to earn additional lives at levels 8 and 16!
