I try to speed run that place every chance I get. I die a little inside every time other party members want to slow down and detour for all the little tiny garbage chests that only drop like 2 bronze pieces or some crap like that.

4 days in a row I've gotten Sastasha with my lvl 40+ monk.
You get whatever people are waiting for a role for. Just so happens that most people are doing lower dungeons.
Sounds a bit counter intuitive but if you're really sick of the lower level ones in roulette just queue for a higher level dungeon for a change. With the buffed exp it's not that much different than running the dungeon in roulette. Especially if you pick a dungeon close to your level.
I've got 1 queue into SV and one into DD, but never got a primal past titan yet.
