One thing I'm rapidly discovering--I've gotten spoiled by the recovery amounts on my main, water healer (well, mostly water healer; I don't have Sun Quan yet...well, I have his Mini version, but...so I've got Echidna and King Shynee in there for the non) team. The rather small healing for my Cao Cao team (even if they are only around L50 on average; subordinates are Blue Flame Ifrit, Theurgia, Misato, and King Flamie) is proving irksome to me.
EDIT: Meanwhile, what's taking GungHo so long to develop ultimates for Blue and Jade Sonia? They've got ultimate Red for a guideline, so I don't understand why they're leaving this irritating asymmetry around. (And really, it's just the asymmetry that bothers me; I don't use any of the Soniae. All right, ally Red Sonia for my Lu Bu team, but that's my secondary team at best, compared to my Eternal Idunn team.)
