Yeah but while I loved WotLK at the time as much as the next players the LK/Arthas showing up in every quest zone giving you the "I'll get you next time you!" line made him less badass imo.
Him in Halls of Reflection was kino as hell and THOSE kind of interactions with the end boss is what makes you respect their power, not them shaking their fist at you for the fifth time after ruining their plans for the zone.
