questioning hunters being buffed? as for being OP....hope you aren't speaking as a h-pal
hunters are only powerful in low brackets, once you get to around 35+ they become weaker and weaker. i have a 70 hunter, they are trash in PVP, only does good if i am on the better mage/priest loaded team. at 85, most hunters do PVE, they aren't really viable in 2's and 3's unless timing some rigged games. yeah there are some supposed "rare" good hunters at 85, but i question those, cause more than likely they are running script/automation built into their macros
overall the new buff is based on what is happening at 85 whether in PVP or PVE, problem is that they will more than likely do a blanket buff, meaning every level below 85 gets it if they are spec'd for explosive shot. they do this with other class too, like mages....which is one of the reasons you see arcane mages in 19 bracket starting like 4-5 months ago from a arcane blast blanket buff. 70 arcane mages also popped up, real fun playing 70 and getting hit with a 11000 crit arcane blast and seeing cheat death pop instantly
while other classes when you read patch notes they state buffs/nerfs are at 80+. blizz is inconsistent on their application/changes affecting buffs/damage, which tends to cause serious imbalances at lower levels due to some classes getting buffs intended to affect 85's
overall, i feel the buff to explosive shot should be done at level 80+
