If you want to go through all that work you can. Keep in mind that unless you are a bot, changing 3 weapions after every attack adds delay onto your reaction time of casting the next explosive kunai.I could just go and hotkey weapons so that I could go between huuma and daggers for the two skills =)
However, what do you have as your secondary skill Jaye, if you have one at all? Or you just pretty much utilize kunai explosion to the exclusion of anything else?
I cast pure soul, fly wing, use pure soul again during its delay to aggro enemies on screen without putting myself in a skill or animation delay, then I 1 shot KO everything that crowds around me with explosive kunai and fly wing. Finishes the mid TI in like 12-14 minutes. My "secondary" is throw kunai which I one shot things with if there isn't enough on scren to warrant an explosive kunai.
