there was this lvl 50 paladin that ganked me a few times yesterday.. So i hop on my pvp priest which I had parked in the same area.. wellll.. he had speed hack as far as i could tell.. because when I finally found him he was basically running circles around me.. He could be right next to me and gone from sight the next second.. god it pissed me off..
(yes I understand paladins have speed buffs when mounted and trust me it was more than that... he had +5000% moving speed or some BS)
