EI is the same thing as EE 2.0
It is not. EI has regularly scheduled resets, EE 2.0 will not, there will likely also be different configs.
The former difference may sound minute to some, but it does have the effect of attracting and repelling certain player types.
If you know all you will ever do will have no effect after 6 months[or whatever the reset schedule for EI is, I don't recall exactly], then is there a point in doing anything, that has no immedeate reward outside of the game?
Now, it is true, that EI allows a single faction[from what I recall the strongest faction at the time of the reset, correct me if this is false] to retain their homebase, excluding docked ships.
But what would you do, if you knew, that regardless of how good you are and how much effort and time you put into the game, your faction(s), will never be able to exceed the faction, that could currently keep their homebase, would a reset occur?
This difference alone eliminates a large amount of competition between both servers, as they attract different playertypes.
