Where do you get epic armour at lvl 70 in wow after wotlk came out

Simple.
Non hero classes, which are the original 9 (shaman, hunter, rouge, warrior, paladin, druid, preist, mage, and warlock) Can do battlegrounds for honor points and marks of honor to purchase pvp sets from the pvp vendors located in Orgrimmar or stormwind. Death knights can only get lvl 70 weapons or lvl 80 armour from pvp.
For better epic gear, You can raid instances. The best raids for gear are 25-man black temple and 10 man- kharazan. Again, all clases except for death knights can have a tier1-6 armour set *-BUT-* death knights *CAN* have the lvl 70 dungeon sets which are not class-specific.
Either way, I recommend leveling up to 80 and running naxxaramas for the best gear of all time.
