I don't have nearly panpiper's experience, but I just wanted to chime in and say pretty much everything he said rings true to me. I've done martial arts as well, and fought with a number of different weapons and in different styles and his post matches up with everything I've experienced and read about fighting fairly well.
Thanks panpiper for a great post, I'd love to fight you in virtual reality some day
Omni: From what I can understand of what you've posted I do like the way you're handling the mechanics of 4th age, great work so far.
