I will never ever get why people think TBC ws such a great expansion. A lot of the raids where just straight out horrible(SSC? GOD AWFUL UGLY NAGA), the gear clown themes(except t6) the EXTREME imbalance when it came to classes. Imbalance in tbc was even worse then vanilla and it has never been as bad since then.
People who think thc is the best expansion best take their rose-tintet glasses of soon.
