From what I'm gathering Kuja will never really run out of magic for the most part. I don't think he's underpowered at all. Of course all the grinding required to get those units to max 5* is no small feat.
Took me a week to get Kuja from 3 to maxed out 5 stars. Not that bad =) . He does run out of MP, because not all enemies use MP abilities. It's rare though.
Also, his attacks are much better than the other mages (physically), so that's a plus I guess. He's not useless when his magic doesn't work. Remember that equipment grant abilities (like the ice rod gives him blizarra etc...), that's useful.
If you have me as friend just test him out.
Wait, rerolling only applies to when you start the game right? Can't do it retroactively?
You can, but you'll need a new facebook account.
Awesome thanks for the advice
Any tips who I should be shooting for??
Thanks again!
Honestly, the best advice I can give you, is roll for one character you love (it's so much easier to play when you have your favorite !) and one character that's really really good.
Kefka, Ex Death, Chizuru, Vaan, Cecil, Roselia, basically any main hero or villain will do. (even Kuja that's currently not as good, is still a monster when it comes to PvE)
Ideally you want a good mage, a good melee dps, and possibly a healer/tank if you can.
Once you have a team you like, save your lapis. Use some of them to increase your friend list, material slots etc... But don't summon.
Only summon when you want a hero really bad, or to get OP characters.
