I really liked TBC honestly, the class changes were sooo good and brought life into my now stale Tauren shaman once again. It really is an expansion than embodies Classic+. It really does just feel like an extension of vanilla, whereas Wrath served more as an update to the aging systems. I wont lie Outland did get stale a lot quicker than azeroth did and I didnt get too deep into the endgame, I raided up to Zul'aman and serpentshrine and that was it for me. Queldanas was refreshing for a while and the dailies were fun for a few weeks. Overall solid expac but wouldnt play it again.
