Exp from level 50 dungeons - Timetable?

[Musashidon]

Then just let them speedrun ... who the hell cares?

se does which is why this isn't a thing yet.

If you adapt xp to the average completion time or give meaningfull reward to high level roulette then it can be okay, right now all roulettes give less XP than an HW dungeon which is stupid.

it's just suppose to be a nice boost. nothing that is suppose to be better than new dungeons, it was purposely made this way.
