Why are there so many bots in swiftplay?

Its always the same. You go into game and you get a bot. Those bots do basicly nothing except running down 1 lane or endless jungle farm.

I mean yes its a speed mode, yes is beginner friendly but how the hell can i try to carry if its always a 4vs5 and sometimes even a 3vs5?

Those bots really take the fun out of it.
