Player position is not very critical in WoW or similar games. Combat is mostly selecting an enemy and attacking it. Or selecting enemy and casting a ranged spell. The game is designed with this server lag in the mind. Servers can easily sync player positions once per second and the clients would happily interpolate between prev & current positions. You are probably seeing things a little late/different than server but it does not matter.
