Do you really think that Blizzard would keep that outdated mechanic for another xpac, as well as focus the lowest level talents on something that would be used rarely?
guardian druids having 3 attacks that also slow 50% will be the new warrior FC imo.
19 warriors had some brief sunshine in wotlk, till cata nerfs rolled, and appears Blizz has a hatred of warriors overall and the low level nerfs make no sense
