Sett Should be Banned from Urf and ARUrf For Now
My reason for this is because this champion is too new and thus not completely tuned for balanced gameplay. Although Urf is about breaking stuff at extreme levels, Sett presents a problem in the fact that he hasn't really been tuned properly like the other champions. Aphelios may be new, but even this champion has received changes to make him reasonable. I have to say any champion released within a specified time frame of Urf or ARUrf's release should not be playable in that gamemode. Playing against Sett in game, I can tell he has weaknesses, but really so many strengths that they can clearly overshadow them. In Urf, this is so many times worse and almost not fun at all.
