Yeah I'm trying to hold off 100%ing my file so if/when a continuation is announced I'll have something to play to gear me up.
What kind of characters did everyone make? I love the Mastermind (I think that's the name) class. I could get about 60,000+ damage to multiple enemies in an attack with the ray gun. auras boost arts damage, knife arts lower enemy's ether resist, then position my character carefully to hit the maximum number of targets and use ranged arts. Very satisfying. Also having heal-all arts and debuffs that prevent enemies from using skills are very nice to have. I was able to do the final chapter without relying on skells (well, for the most part. they all broke pretty easily).
Oh, plus I added a magazine augment to my raygun (I used the weird-looking ether one that powers up the virus debuff) so it could get more hits in. Used the knife for a quick boost of TP.
