'Claws' in any stance is a 'fast' skill, it suffers no post-delay, any skill used after it will fire instantly; most noticable with shadow pack [the -mit pool] can be fired off without delay in combat (bestial claws -> shadow pack -> eye rake, your leg will barely raise to pee).
'Eye Rake' used to speed up your own rotation/skip animations (i.e. after using shadow pack)
'Piercing Claws' usefullness is based on how much morale your opponent has (I typicly ignore the skill if its less then 10k) although it will do 10% instead of 5% on a crit. so theres that.
As for an attack rotation, claw and maul have that nifty crit bonus in shadow stance from 'element of suprise' the other attacks are just filler when those are down.
(sense im here I might as well throw in my plea to have all flayer wargs report 'raking claw brute bonus' as bugged. a debuff we have no control over, that will overwrite/supercede our -atk speed debuffs, it should not be in the same category, being an induction debuff that we only really need for an LMs water-lore [not saying that flayer will help you vs an LM])
