So what would happen if you eliminated the Jump button and made a defense roll and a dash move to replace them.

What concerns would you have for such a situation.

What Advantages do you see for such a thing.

What Disavantages would you see for such a thing.

This thought exercise brought to you by a friend of mine who asked me what a fighting game would like without a jump button... I wanted to know what other fight game fans thought of this.
