Udyr Tiger Strike is under Persistent Effect Instead of Activation (In Game)
So just a little error in the description for Udyr's tiger stance IN GAME, but his tiger stance active effect "tiger strike" (damage over 2 seconds) is under the passive/persistent part of the ability description.
It's always bothered me cause if it's gonna be under persistent, it should re-proc the tiger strike effect after 5 seconds (as with the bear strike stun). If not, the increased attack speed is just lonely in game knowing tiger strike description should be next to it. :b
