Theme wise i did not enjoy MoP very much, i was actually really looking forward to the MoP style of art and more, but i mostly felt as if the major colours were green and brownish once i started playing. There was only one raid that caught my eye and wanted me to actually start raiding this expansion and that was ToT. But after i cleared that i wasn't very keen on raiding it again. But yeh, cataclyms was my favourite expansion with the lovely twilight theme and bad ass raids (even thought DS sucked, i purged that from my memory bank). But all expansions had that one raid which was bad if you ask me. Maybe ill go back to raiding in WoD though =)
