SE could you please, allow us to change class mid dungeon, when someone disconnects, and we're out of combat?!

It's annoying, that some tanks, find themself entitled to do a shitty job, and get pissed, when everyone else, is trying to help them do better.

Especially because the party is doomed to fail, due to the absurd long waiting times, to get a new tank. And i believe, that if someone in the party, is willing to change class, in order to complete the dungeon, they should be allowed to do so, without leaving the current party, as long a member is missing for a light party, and we're out of combat, i can't see a problem with changing classes, to adjust to the new party setup, once someone leaves.
