Being DC'd at the Ascendancy Altar

this isn't a post to bag GGG on THIS issue, but i do think they need to update their use-case scenario regarding the lab to at least grant you the ability to choose an ascendancy OUTSIDE the end of the labyrinth, assuming you killed izaro in round 3.

if you DC before you open a treasure chest or fail to enchant an item however, well, too bad. but to lose your chance to choose an ascendancy class, well, i think that's just plain unfair.

dear OP: maybe put this forward in the "suggestions" forum...?
