We were at something like 7% Arena representation in 3v3, in S6-S8. Now we're at 1.5-3%, depending on what rating (obviously the rep gets lower the higher the rating). Back in WotLK, we could disarm, drain mana, kite, do very good burst, and actually avoid incoming damage. Nowadays, we have Focus, which is an awful, broken mechanic in itself. We cast more than casters, have an extremely slow resource regeneration (that is tied to a casted shot that's canceled from LoS or someone getting to close), and have very little mobility because Master's Call is now dispellable. Oh, and we're all at sub-5% Dodge because of a substantial Dodge nerf that we took this expansion, and no self heals -- so we have effectively the least survivability in the game. TL;DR - Hunters have crap damage and survivability, and when you face an enemy, you hope they're really, really bad.
