I'm really hyped for demon hunter, artifacts weapon and legendary items. i wish that they can change a bit classes's itemization. New warrior look like fantastic, as well as the new raid.
I started playing wow in tbc, in 2.4.3 patch, discovering Black Temple raid, Illidan's lore, and the magnificent world of wow. I really liked many of the changes have had so far, and i hope that this expansion is fantastic as the others.
