you really need Build Up.
I would drop an aoe..Burn would be my choice. Also you have 9% Acc bonus 6 times in your build..anything after the 5th will not count
Guassian's (in BU) will give you more even more defense
Whirlwind is pretty much worthless 
you need knockback protection (i put a karma in CJ)
Armageddons would be better in FSC.
perma jump is ---> /up 1
Combustion and Short Circuit is a tedious and dangerous combination. One or the other will be fine.
Luckily, you don't need them both. Ball Lightning, Short Circuit, Fire Sword Circle all while Blazing Aura and Hot Feet are running is enough AoE damage to fry the ears off a gundar.
