The problem with using a smurf at all is that you're not going to be dialing down your skill by playing a support or the like, any experience you've gleaned is going to elevate the success of the team.
I am well aware of that. That still shouldn't put me against 400 win stacks. As I said. If I play a team full of 50-60 win people. That would be completely all right with me. I can accept that. Hell even 100 wins. I don't care. At least we have a chance of winning by good team coordination.
