MS is a horrible tip for anything....

Why is MS a horrible tip guys, it gets knocked around too easily and when it gets hit hard it topples over, isn't it supposed to try and keep spinning? I also noticed that it doesn't spin for as long as WD, isn't it a Stamina tip? Hopefully you guys can answer my question.
Thank You.
