Samurai rotation at 70 help please

[Shizzle]

Edit: iLvL 310 eh? It should be more than enough. Keep trying![/QUOTE]

Ok I always open up with Kasha opener for the speed buff then from there hakaze into yukikaze then kaiten + higanbana then from there I add onto my hakaze jinpu into gekko so I have both the damage and speed buff as well as the slash down and dot on target I do try to use guren as often as it is up as well as 3 zen kaiten midare setsugekka . I however am trying to figure out where in my rotation to fit Shiten in as I usually dont use Shiten alot :/ Is it because of not using Shiten that often really causing such a large decrease in DPS that has me worried if so :/
