Nah, sure kami's epoch heals a little bit more than healing wave, but the CD is very long, so if you are willing to pvp you'll get destroyed easyli, even in hard PVM like soloing a Boss (yes you can i already did it few times) you'll need healing wave, cause it heals like 500 less but for 15 seconds smaller cooldown, so lol...
also kami's determination maxed is only good if you are using crit % gears, wich is bad for poko's, you need a huge focus effect on your staff and atk speed on sub weapon, wich will synergise alot with kaioken and kami's blitz.
also, the red dragon deals pretty good damages too, also maxed gives you a boost of 100 energy atk almost permanent, so fujimaru your build isn't that bad but it isn't good either,

+1 point on the dragon summon (lvl 5 max), +2 on kami's blitz (lvl 4 max), +3 on poko's curse (lvl 4 max) also the buff removal increased to lvl 2 cause it's like shadow knight's life steal, it drains 107 LP but can deal way more damages, for exemple i did - 300 on a mob once, it can help.
