This is the advance CT mod edition.. it comes with the Core mod it self and CT raid assist those 2 MUST be enabled while raiding with TBO. The other mods that comes with it are free choice for enable or not.
I played Classic until I was nearly level 60. It needs The Burning Crusade really for me though. I am lurking around Daggerspine again for a while, trying to get used to the changes lol
