I wouldn't mind a Bastet buff, but I don't think she needs one. Horus certainly doesn't.
I would, however, like a second ult evo for Bastet.
If anything, I think Bastet's only upcoming buff may be delicious G/L Genbu being healer. Otherwise I think there's reasons why her leader skill isn't really changeable at the moment. (I.E. Dropping the combo req or increasing damage threatens Oku a bit- though since they're giving JP2 ultis now, I don't see why they couldn't buff him too)
Horus... Honestly? He has issues now. A lot of better options are popping up. I don't think he's in as good a place as he could be, and I think he's not really on even ground with a lot of other burst teams. He could use a bone really.
isis can cure 3 turns (it is 3 right?) of binds on the whole group on a cd of 3 while being bind immune now, so I wouldn't really discount her as a leader-only god anymore.
Isis can cure 2 turns on 3 turn cooldown now. Which, while still kind of a small amount, is way better than 1 turn and straight out the -best- cure heal in the game for turn efficiency and only challenged by shower of healing use against stronger binds isis can't handle. She's also the only smaller bind heal that is bind immune.
Isis is in a really great position right now, basically. She might even make it in the next popularity godfest!
