To be fair (warlock with a hunter alt as well), a hunter has to actually work on their pet. Levelling one is grueling, even with the instantaneous levelling they get when you train a low-leveled one. Our minions are always at our level. And a hunter is at a much greater disadvantage most of the time when their pet dies, unlike us who don't rely AS MUCH on our pet to be functional.

I would get a little pissed off if Hunters did have the ability to summon pets with as quickly as Warlocks do, however. Maybe give the supposed Hunter move a five minute CD with an inability to cast while in combat, and if your current pet is dead, you have to revive it before you can summon another one?

Leveling a hunter pet hasn't been "grueling" since they gave us X-5 level pets.

Prior to that, sure. Getting Humar from 23 to 70 so he could be useful in KZ raids was kind of irritating, but "grueling" still seems like a stretch.

Well GC does have a point. Technically if you have dual spec (if you don't, get it now, don't be cheap) then you do get to summon any pet at your stable with no cooldown because every time you change specs the call stable pet spell renews itself, and there is no way they can nerf this because if you're a BM hunter changing to a Surv hunter and you had an exotic pet out, you would get screwed.
So stop trying to get them to do something about this because we already have it pretty well and instead ask for the 1minute trap duration back and to not implement the internal cooldown for LnL, i love having 2 freezing traps in a row and 5 explosive shots in a row.
