Kunark was a jungle continent, it had ~2-3 desert-ish zones. TBC was a charred wasteland, not so much desert so don't really see any comparison there. You could make a comparison between Velious and WotLK, but then again WotLK was just mining into a pivotal lore that was already years old by then and entrenched into the franchise (Arthas/Northrend) not really an "EQ did snow 2nd xpac so let's get to it" situation. Third xpac is a return to basic continents with no new continent or world so I would say it is decidedly differing from EQ's #3 being a new planet and slight genre change into a bit of sci-fi. You say to-may-to, I say to-mah-to.
