I am leveling up my warrior, now level 88. Keeping threat is not an issue except when I meet hunters using Kill command with their pet. Any mob or boss they aim for I loose threat, becaue their pet creates extraordinary amounts. It is not a growl/taunt matter, for that would make their threat equal to mine - instead, threat from the pet is insanely higher than mine (even when the hunter produces much less dps). Taunting back is not a solution either, because 1) then I loose taunt for dealing with threats to, say, the healer and 2) the cd on Kill command is pretty short, so I keep taunting.
Right now I solve this by simply letting the pet die. But... there should be a better solution involving me keeping agro. Advice is welcome.
