Leatherworking

[furien]

Hey i have my lw up to 600 and i can make magnificent hide but according to wowwiki i should be able to get the plans for hardened magnificent hide from a random drop on the timeless isle and i have killed a lot of things there and i got a lot of different plans but not this one so i want to know if it is even possible to get it on this server or if there is a different way to obtain the pattern or if someone can tell me how to make epic leather armor because i can only make items to lv 450 at the moment
