With the very limited number of debuff slots going into deep wounds and in turn impale will negatively affect the raid. Now in retail there was also a problem where if you crit before deep wounds' first tick than the time to the initial tick would reset basically causing deepwounds to do no real damage. because of both these problems this is the fury tree i plan on raiding with.
