Something I've noticed. When I get thrown into Praetorium via the Duty Roulette, sometimes I will gain a full level. Sometimes I overlevel. Or, like just 10 minutes, I get 60% of a level. And no it's nothing to do with whether my role was in need when I queued. Or my level. I'm in the level 80 range, and I've had runs on other jobs where my role wasn't needed and still gained a full level. This time I was tanking and tanks were in need. Still got barely any experience.
What is the point of doing this roulette if I can't be certain whether or not I will get more exp than a regular dungeon? Especially considering I get near insta-ques for anything as a tank. It's bad enough that the roulette exp overall (not just MSQ) is pretty weak, but for it to be inconsistent is just making me not want to do it and just dungeon spam and run fate trains.
If anything the duty roulette should tell me the exact amount of exp I will get. I'm tired of sometimes getting good exp and sometimes getting crap, especially with an instance that's 45 minutes long and 70% unskippable cutscenes. I just don't understand what the reason for the inconsistent exp is.
