Normal Infrit in the Leveling Queue...

I always was hoping to get it so that my daily roulettes would take less time. 300 experience seems odd. Had you already done the roulette that day? The daily bonus only applies once per day.

After doing it once for the daily bonus, it's better to directly do the highest level dungeon that is in the level ranges 1-49/51-59/61-69/71-79/81-89/91-99. This is because 50/60/70/80/90 dungeons were once max level dungeons and just like quests of those levels, they don't give as much experience, as they are not considered "leveling dungeons" or "leveling quests".
