Hiya.
Few thoughts that came to my mind as a newbie ninja.
1: "kick" skill could get some boost from martial arts as a
"mastery" causing it to get modified into jump kick/roundhouse
kick/back-kick/something ninja. This could use more ep's and make some REAL
damage.
2: Martial arts are pretty shitty nowadays and it could get some boost by
making it somewhat similar to stalwart stance(auto-launch iron palm/kick/what
ever). Just to even look lil more cool
