Did some play testing last night with these guys and made some changes to the cards. The Foot Soldiers were indeed over priced in my opinion.
Also, I figured out how convoluted it is to give a squad a special attack. Does everyone have to use it? How does it work etc. So I nuked the power and gave them a different trick. They really are a pretty close replica of the Ninjas of the Northern Wind. But that's ok with me for now. I adjusted their point cost as well and I think it is more appropriate (They have 3 figures instead of the Northern Wind figures count of 4).
Here are the new cards:
Foot Soldiers:
Foot Ninjas:
