You missed the specific EX charge attacks for the technique types. Not all of them have a normal R1 for their actual Type Action special like Zhuge Liang and Musashi. For example: Dian Wei, Zhao Yun, Xu Huang and Hanzou have C3-EX-SP (S, S, R1) Cao Ren has C2-EX-SP (S, R1) Kojirou has C5-EX-SP (S, S, S, S, R1)
My favorites are Ina's and Ginchiyo's. The first is really really good for pacing and you can sorta abuse it to do cheap damage in case you in a pinch, and the latter is amazing for crowd clearing and its quite strong.
