No, this does not mean hacks and exploits such as the other thread that enhace your gameplay and give you an unfare advantage. these are glitches and exploits more so in the terrain.
some of my favorites are
getitng under stormwind
getting under orggrimar (specially as alliance)
getting into old ironforge
getting ontop of that valley in between elwyn forest and burning stepes
anyone know of anyothers? i know theres many out there but i havnt seen any. for the ones i listed if you guys dont know how to, you can find many videos and guides to them on youtube.
*these are not against the rules to do and you will not get in trouble or punished for doing them such as hacking and doing other things along those lines*
