I've been thinking alot about what will happen with achievements, that are no longer accessable in cataclysm. Will they become FoS's? or will they just be removed?
I know they will make a new Loremaster achievement, but what happens to the old? will they get any creds for having it done before cataclysm?
also, Cataclysm will make the zones new, giving them new maps and new areas to explore. Will they reset Explorer aswell? maybe we get Old world Explorer or something.
as a side note, ive never played in neither TBC or vanilla, so i dont knwo the "routine" on this, but when the dungeon finder came out, i saw that i got one FoS for completing all daily dungeons.
