I don't like any of the ideas except the set bonuses for gear but even then it's tough to balance that out and it'd favor more classes to bring X job instead of Y. For example if they made something like idk 4 set for Mch gives hypercharge +5% more dmg from physical and magic attacks where bards would get something like your bloodletter when it resets has a 50% increased crit rate. It'd have to be balanced pretty hard to achieve this. Again just pulling his outta me arse.
