you put higanbana kinda late
@1:02 you used midare even though hagakure had ~4s left on its CD, you could've done hakaze->jinpu (hagakure)->gekko
@1:17 hagakure used with 2 sen instead of 3
@1:25 you used yukikaze combo to setup a sen for higanbana, yuki combo has the lowest potency
@1:45 you did hakaze->meikyo->yuki essentially wasting a "charge" of meikyo
@1:54 midare when hagakure has 2s left on its CD (again)
@1:55 shifu ran out, instead of refreshing it as quickly as possible you did a yuki combo first
@2:05 jinpu ran out
@2:15 when you see that guren has 5-10s left on cd right after using hagakure, hold kenki for it instead of spamming shintens
@2:42 the higanbana you put here was a dps loss, higanbana needs to tick for at least 45s to be a dps increase

+im guessing your gear is kinda meh, try to aim for this http://ffxiv.ariyala.com/157NG
