Started my journey in MMOs when my mother accidentally bought me Dark age of Camelot not realizing it was an MMO that you needed to subscribe to. Love it. PvP was so much fun in that game. Sieging castle from low levels to fighting massive realm vs realm vs realm wars.
Played basically every MMO that has come out since then. Enjoyed bits and pieces of them all but the big PvP ones will always have a special place in my heart. Like the Warhammer MMO as well.
