So lets just imagine for a second.
In about a years time, when Kel'Thuzad is dead and more and more guilds are beginning to clear max level content, will the developers behind the phenomenal Nostalrius ever be inclined to release the Burning Crusade as an extension to Vanilla (perhaps a free server merge) as a way to keep the influx of players growing? From what i've played of this server already, i'm loving it, and i'm willing to invest quite a lot of my time into progressing my character. What saddens me is the thought that after i've achieved all I want to out of a vanilla realm that there will be no progression beyond that, and should I want to move onto a TBC realm then i'll have to start all over again.
I'd be interested to hear your thoughts on this.
