Kewl, I'll make sure that you can push any kind of stats with the next push. Right now Arena characters come off a bit weak and have a very low hardcap. You can do that with pure experience as well right now.
PS: Arena Character are not mobs so you should specify the exact strength you wish them to have instead of relative strength as percentage.
I haven't played the game in months (if ever) so I have no idea about the balance

. I've just copied the values for "Randalf" and adjusted them a little.
also I didn't pay attention to it, because without more skill types, new teams are just different pictures atm...
May I suggest creating a possibility to add customized pre-match and aftermatch events for teams? Something like adding a field in arena_teams.json with name of label the game will jump to? (Or automatic team name label like in GM) For stuff like different taunt line, team pic, different music, first introduction event or to set flags for quests (=team XY defeated).
Also, it is possible to set affinities for NPC arena fighters?
btw. I'm for the guns. After playing few FF games, sword vs machine guns doesn't feel like unusual combination in the slightest
