This part really confused me as well. The other thing that I was confused with(as someone who played the beta) was if they knew play style could have an effect on server load, why did they have such a restrictive beta? The beta was short and greatly limited what you were able to do, so it seems logical that it would not give a fair representation of how people would play the game. I think if play style was an issue then they made the mistake of using the beta as a marketing tool, rather then as a method of testing the game/system.
