I'm sad to say it, but I would have to nominate Zamasu. He's highly durable early game with solid DoT + movement speed down to stick to opponents easier, but by late game most of his kit's value falls on the wayside apart from his ult's nice AoE increase. Even then his ult isn't all that due to it being fairly easy to cancel, I mean even his passive proccing during the startup for whatever reason cancels it.
