Is Leveling Roulette (and other Roulettes) giving subpar EXP as opposed to before?

[Nyarlha]

how much of a diff would you say?

Between Praet and Castrum? I don't remember the numbers exactly, but enough to be noticeable, i'd say around 10/15% of a level?

Add to that the fact that despite being shorter, Castrum actually requires more engagement from the player than Praet, honestly I think both should give the same xp.
