First of all I play exclusively casters this might skew my opinion a bit, but hunters are just like rogues broken on casters in my opinion, and just like rogues ( removing prep) Hunters are in my opinion easy to fix.
Right now hunters have massive range (same as casters, but they can use it while moving without any sort of snare like KJC) and no way of getting away from that sick dmg in bg's, I remember the good old days when hunters always died on Marrowgar, they had a range requirement back then, I understand that in Pve this is a quality of life change, but this was never neccesary in PvP in my opinion.
Right now hunters are incredible dmg monsters that mostly got buffs they didnt need in the first place( Powershot, talking BM mostly and mean in the course of cata till now, not last patch), melee and casters alike are getting kited but usually just bursted down with auto shots, while some six year old is clicking through his spellbook. I have heard people say that hunters have a high skill floor, but I doubt this is the case( dont have a hunter) anymore, atleast rogues in arena require an even amount of chromosomes ( barely ).
On my lock and sp i really have trouble countering hunters cause they can fd, deterrence, disengage, readiness deterrence, camo ( pre combat) , powershot, knockback trap, stun, silence, icetrap. these are all cc's that can serve to open a gap, why do hunters not have min range anymore? Just like shuriken toss for rogues, not having min range makes hunters melee instead of ranged, hunters were by no means easy to counter in open combat to begin with, even in some arena maps hunters kan hit you from anywhere. It also doenst make sense from a lore perspective just about as much as a mage critting for 30k white hits while meleeing you with a wand does. Have you ever shot an arrow from point blank range. Hunters always were good dd but they had their niche, know theymight aswell wear plate and gem strength they are melee, but if they are shouldnt they have a smaller range?
To me its either revert min range in PvP or decrease range in PvP. right now Hunters are uncounterable for casters without obstacles, and some arena maps barely have obstacles.
I honestly think that pvp would improve with this change alot, some would call it a nerf but I would call it reverting back an unnecesary buff.
