The whole priority system could be improved. I remember Higurashi suggesting a better one somewhere. A definite improvement would be to use all buffs as first action in a turn (takes care of PU and Devour issues, for instance, as well as Dive issues). Also, playing Hasten before other abilities is sometimes more useful too. Finally, some better targeting method when Rays of Light and Hope are up (it's ok having a higher priority for RoLs, but I mean, Twin Universe targeting them over a 40ish attack creature?).
