Its mentioned a couple of times, but cannot be over emphasied with a hunter the temptation is to stand well back as then you can SEE the fight and what is going on, epsecially when your rat it is easy to select next target etc. I understand this and why hunters can often be a good raid lead class, tanks have a Diabolical view of whats going on normally. (which is why you shouldnt rely on tanks fixing other peoples problems as in multi mob pulls the tank is often the LAST to know what is going on)
BUT if the situation calls for grouping up for distributed damage GROUP up... (recent pet hate)
Certain mobs it is better for hunter to stand in melee range (corruption removal, interupts, speed focus gain) maybe doesnt fit 'optimal dps' rotations but hunter IS a flexible class if you allow it to be. Also as pointed out healers cannot heal you if your out of range , and again healers are busy watching your health bars, there positional awareness is lower than most other classes as there job gives them a different focus, screaming heal me is pointless they probally have already wasted valuable time trying to heal you but your where out of range or LOS. Also while talking about other skills rember you have posion removal for a reason, not all poisons should be a hunters job, but attack speed debuffs on the guard, poisons that silence the mini effectivly render them useless. Cant remember the exact range on posion removal but I am sure it is less than max range on bow!
If you get aggro , consider how close target is to death and if it is trash or not, a single trash mob in many dungeons should not be any threat to hunter. Pop out your parry increase, let it ping away as you burn it down or dazing blow it and blast it.
If the aggro mangement is important (stay within aoe leech and threat range of the tank) else they have no way of getting it back without chasing around, and a tank should NEVER in an ideal world have to chase mobs, how can they keep aoe frontal cleaves away from the party if they are running around!!!!!!!!
If you get aggro, kiting should be a LAST ( very occasionally it is necessary ) resort, running around screaming gets no where. Melee DPS can not be effective playing benny hill, a guardian has problems hitting to take aggro back if they are playing benny hill , aggro generation on other mobs chasing the chain is decreased making it more likely healers will get aggro it tends to go pear shaped very quick.
Aggro dump run through the tank melee group, when mob is in place hit dazing blow if you have it up to sit it in place get out the other side and swap targets or go low threat stance for a while. At least this way as well if you die the mob is in a good place to aggro straight back onto the tanks who should still be high up the threat list.
