SM 4/5 revive
Paladin 3/5 revive
Succubus 3/5 revive
Should I reroll any of these?
What I would do is hold onto revive for the sake of leveling them up more quickly (since they will survive longer in raids). You could roll a lot worse talents. If you plan to reroll them eventually then maybe you should just go for it since those aren't the best for arena but I'm sure they could be pretty useful
I find revive more useful when defending rather than raiding due to the fact of Heroes/troops switching targets. I find it great in defending when on a Ninja/Assassin.
You should essentially re-roll all of them, but like people have said you could get much worse talents. In Arena, Revive for SM is pointless due to the fact that it is usually the last or one of the last to die since it is ranged. If it does end up reviving, it will just get killed again most of the time.
