so far no is winning
As hinted, this should be expected after many players spent 4000 Diamonds on him in Soulforge a week ago. 
Besides the poll is too simple. Many Players don´t like the current status, but would prefer to change the Divines instead of this single card.
I agree with others that isshbala is the problem. If any changes I would say attack the “2 strongest”.
I don’t have Ubastet but I lust for him like most people.
He probably should be nerfed if only for the previously-mentioned reason that it makes no sense at all that opponents’ attack is factored into his ability.
However, I have no problem killing almost any Ubastet PvP team unless I get an unusually bad starting setup. A couple spellcasts by Divinia buffs all my troops’ life to the point he can’t one-shot and he doesn’t get a second chance 95% of the time.
