Did they nerf dungeon XP recently?

I seem to recall roulette bonuses not giving as much exp at 80 as they did at 79 or 81. Are capstone levels different for exp rewards from roulette?

It gives proper amount of EXP, but scaling of 'round' levels is off, because things provide EXP amount appropriate for 71-80 bracket, but exp needed to go from 80 to 81 is appropriate to 81-90 bracket.
