best combat experience you've had in an mmo/expansion

so we've seen many games change alot in terms of combat experience through different expansions and balance/mechanics updates

what is your best one so far?

for me, it is black desert first 2 to 3 years and i think nothing even comes close.

every class was just perfect, pvp was so good and i had the best time fighting and learning from some random guys in arena. then they started releasing these new classes which were fun to play ngl but the dynamics of the pvp became worse and i couldn't care less. maybe it is just me tho

then comes wow wotlk. i haven't played all of the expansions but wotlk is the best one i played and it was amazing

what do you think
