Hi All, From my understanding Elysium will become a TBC server once progression is done. I wanted to know how that will work. Will the whole server progress or will you have a choice to stay in Vanilla land and copy character into TBC server. Im asking cause im just starting otu and I figure it will take me 4-5months to get lvl 60. I dont want to do the whole grind just to find the server progressing to tbc a few months after im done. Thanks guys
