Most MMOs don't have the sheer amount of relevant parameters per player to take in consideration during the fight.
Usually you have something around 20-30 parameters, life, dmg, resistances, position and movement and maybe a handfull more parameters.
In eve the number of parameters explodes exponentially, for example, no only your position and speed is relevant, also your angular speed vs each other ship that is shooting at you or you shoot at.
Add the fact that every player has the option to have at least 5 drones that are basicaly slave ships with their own set of parameters to keep in consideration.Also add that some of the projectiles used to atack enemies are physical entities wich can be atacked and destroyed with their own position, speed, life...
Now add everything up and try to factor that in your comparison...
