I am at lvl 318 and I had opponent between 100+ and 400+. The mojo reward was between 11-17/ fight.
Pros:
I still can get some aff and exp points for the girls;
in the first month I am sure I don't want to spend koban for the second pass, so it is basically free (maybe some refresh if am not far away from a great award)
all the oppenents are changing, not just the one I fought with
Contras:
I don't see, how I can get higher awards, if any
no info if the girls reappear again
I miss the old leaderboard where I could seen the other players performances and mine as well to compare my performance week after week
Concl: it is a nice feature but you don't have to accepted much from it
