Make leveling roulette bonus permenant
I have never understood why this needs to be a once per day bonus. This helps new players level up, improves queue times for all dungeons and gives players a chance at not doing the same dungeon over and over again. I mean the bonus is equal to what you would get anyway had you done a dungeon that was meant for your level.
Even for high levels the tome bonus is smaller compared to 50/60, so they would still do other roulettes over this or spam an individual high level dungeon. personally I see no reason why this can't be a thing.
