My only major gripe so far is that these changes to the old world are PERMANENT and there will be no way to go back once it starts. I was kind of hoping they would implement something where you can go back to the original old world through the Caverns of Time. No such luck though.

And my only REAL concern about that is that I have places like ZG and Karazhan on Farm for the mounts, and I really really hope they do not change those zones at all.

Also, if I ever do boost up another team, I'd like to still be able to take them through Deadmines, Scarlet Monestary, Zul Farak, Strat.

If all that gets left alone, then I'm gtg.
