Speed running, despite being totally contrary to design (albeit not exploitatively so), certainly has its place, and can actually be really fun. However, those looking for speed runs via the random DF probably ought to fire up the party finder instead.

I like to tank, and smashing through a dungeon is typically my default mode, but I make a habit of asking first if anyone looks like they may be new. If they want to watch cutscenes or do a full clear for XP or loot, then that's what we're doing.

For tanks and healers: This is pretty much your tradeoff for those insta-queues.
