1. Do LFR
2. change server
3. Do LFR again
This also works with other raids (Dragon Soul, Baradin Hold) so i guess you can do HC DS and then server transfer and do it one more time for more gear
Small example:
My friend is going on vacation from wedensday and 1 week forward, wich means he will miss a lookout, he then server transfers to another realm (free transfer) and he will be on the same "Gear lvl" as everyone else.
i dont know if this is a repost or common sence.
