Haymaker duration should be extended, not the slow effect but the amount of time it lasts. Maybe it should also give a stack of greased lightning. I love when it procs because it's actually a DPS increase (and it conserves TP). The problem with it proccing is that it never should since you shouldn't be taking damaged. But the amount of potency this ability has is great, so if all Debuffs and dots are on an enemy and twin snakes won't fall off and this ability procs, it IS a DPS increase, albeit a minor one. This is why it should have potency increased, or the counter period should be longer so that you can fit it in properly, OR it should give a stack of greased lightning. Sometime I pop featherfoot and stand in a physical AoE or something if I let my healers know just to proc it. One good application is dodging mortal gaze too.
