I've been playing since global launched. My biggest complaint are the drop rates. I just dropped about 30k visiore and pulled nothing but majority R and SR ranked characters, a few MR's, and even less UR's. I don't really even care to keep up with special events since getting the characters are extreme luck with the RNG and drop rates, or I have to choose between my mortgage or buying paid visiore to have the same horrible drop rate... but go broke doing it. Do better Gumi.
