The differences between WOW and EQ are too numerous to go into.
Namely, pvp style, graphics style, artistic quality and style (i like the flare in WOW much more than EQ), soloing ability, death penalties, crafting system, do I need to go on?
Sure, some of the same old bs exists but that is because its a MMORPG, there is a lifespan of a MMORPG and most of them follow it, including, WOW (much to my chagrin).
Id like to see a MMORPG break out of the Nerf it/Nerf the fun mode but so far WOW follows suit on that regard. (Nerfing fun, least thats my opinion, they like to take whats fun and make it less fun)
