Switch to Roy 4 training?

[Eirei]

Would it be any usefullness at all to switch to Roy from Marth and let my friend be Marth for a little?So I can learn Marths weaknesses and work on ways to cover them up.So is this just another stupid idea or a useful one.

If you like Marth, just play with Marth and you will surely enough learn about your OWN mistakes that you do with Marth. Also, you will find out his pros and cons and things that he can and cannot do.

But it can be beneficial to play as other characters to learn their weaknesses from your own experience.
