I'm working on some of the "family" feats (100 with a Bat family character, 100 with an arcane character, etc.), having gotten nearly all of the others, so I'm trying to cut down on the amount of time-spent-in-instance if possible. I know a lot depends on the other legends that queue in, the experience they have, whether or not adds are skipped, and the like, but all things being equal, what seem to be the quickest runs for you? I've more or less defaulted to Oan Sciencells and sometimes Trigon or LOA. Other suggestions?
Hall of Doom is the fastest with everyone on the same page Trigon's Prison is a little slower, but safer Oan isn't really short because of the fixed dialog, but there's little chance of wipe I pretty much stick with those 3 depending on the group I can form (or not form!).
