Re: (Nutaku) Kanpani Girls
The event weapons roll more like normal gear than the previous event weapons. i.e. +0 to +2 is common, +3 is rare and I have yet to see a +4. In prior events I got +4 all the time.
For the +3 anyway, they are far weaker than previous event gear (even +3 stuff) or +2 chapter 2 gear. Not sure about skills, haven't bothered to look.
They actually recently make completing the "Training Session" much easier to complete by removing some of the more ridiculous requirements.
Some, not all.
