Wouldn't it depend on how long it lasts?
I suppose it could have an additional rule that a team still maintains vision within their own base if it was overused for backdooring.
Actually, that seems very much a sensible rule, because otherwise that'd be it's sole purpose, whereas using it for ganking/escaping is much more interesting.
