Which end game content are you referring to.

To be fair, it sounds like the issue was related to 2x AST, which is hard to learn in basic dungeons where there is only 1 healer. Did you bring any of this up with them during the run?

Also, afaik, AST Sect that gives regen is generally considered better than shields - no? In this case, don't the regens stack like Medica II/Regen?

Double regen is terrible and leads to nothing but overhealing. Any AST that picks diurnal sect when with a white mage or another diurnal ast is bad and should feel bad (though in the case of the latter, both are at fault as either of them could change).
