No, he's AWESOME.
I'm proud of my man Kakashi, i can deny it, and no you're wrong somewhere. Kakashi is already stronger than Tsunade and low kage level. He doesn't need Edo for that. xdyou are known as a ultimate kakashi fanboy so sorry to burst your bubble but he wouldn´t be overpowered he would be quite strong and maybe take out tsunade or low kage level but still not overpowered
Exactly :y:y:yHe'll make use of his 1000 techniques without worrying about his chakra, he'd also use his MS more often and Kamui wouldn't be a last resort technique anymore.
I say it, he would be OP to the fullest.
ObviouslyIf he was an Edo, i think he would be a much worser promblem than Madara lol.
Kamui, Kamui everywhere.
