I play often the 80 Sta Daily Manyu, but that's only because I don't want to Level-up too quickly (because more your Level is high and more your next Level need even more XP). That's a fact it's very VERY bad in comparison with a 80 Sta SG: most of the time I got at least 2 Level 5 Manyus, and maybe 1/3 run I got just 1 Level 100.
