Whenever somebody plays this the opponent thinks "why does he have this one ability that is only good against the exact faction i am playing and gives him +50% dmg?". keep hunter: giant, hunter: slow, hunter: meek and all that stuff, those are good. the end
The problem with hunter faction is that it either works 0%, 50% or 100% of the time in a game. with stuff like hunter: 7 spd, it works maybe 20-30% of the time every game, or some such. which reduces the variance.
