http://www.wowhead.com/spell=185987/hunters-mark : In dungeons/raids with another or more Hunters MM, this spell seems to be a little bug. When I successfully get Hunter's Mark on a target, it happens sometimes that other hunters may "steal" my Hunter's Mark shooting http://www.wowhead.com/spell=212621/marked-shot . For this reason, I can't cast my own http://www.wowhead.com/spell=212621/marked-shot and of course i can't get http://www.wowhead.com/spell=187131/vulnerable , unable to do any damage.
http://www.wowhead.com/spell=194595/lock-and-load : Sometimes, when this talent procs, istant http://www.wowhead.com/spell=19434/aimed-shot drains focus.
http://www.wowhead.com/spell=781/disengage : Sometimes when I activate this spell in midair or in the water, I leap to random direction, and not always backwards.
