We don't know what that limit is exactly which is exactly why I don't like people using DMS Kakashi because it was a very temporary mode that we'll never see again. Of course there's a limit to what DMS Kakashi can do, that goes without saying. But you can't just assume that it's a time limit. I don't see the problem with using DMS Kakashi, it's a distinguished version of Kakashi. It's no different than using Juubito or TTJ-Madara.

So, a limit exists. We don't know the exact limit (in a sense, Kakashi would simply become an Edo Tensei at some point), but a limit exists. Kakashi barely being able to move was after Obito's spirit left his body. When Obito's spirit was inhabiting Kakashi's body, Kakashi felt no symptoms of exhaustion despite whipping out, presumably, chakra-taxing jutsus. Like I said above, of course DMS Kakashi has a limit, that goes without saying. But I still don't understand why it's assume that the limit is a time limit when Obito left Kakashi's body after the threat has been dealt with
