That is not accurate at all in any sense.Yeah, that was my point. If you open up expansions fast, then the lower content is a ghost town and getting a group will be more difficult.
If the expansions are longer , there will be more people at higher levels trying to cap and the server turns "top" heavy , that or they have completed the content and are waiting and raid logging , if the game is "slowed" down the same thing happens in a sense.
If im level 40 + , why go do level 20 content ? I will be trying to grind out the last few levels.
This brings me back to my original point , the rate of a power gamer or someone that is trying to cap content needs to be irrelevant to you.
Those types of players are going to out level and out progress you no matter how you want to slice it, but you need to understand the following.
It does not affect your specific game play at all , in fact slowing it down will prevent me from making a alt that will be doing content that you are progressing through on your first character , because on a slower paced server I simply will not do it twice and concentrate on my main.
Trying to delay expansion unlocks or slow down content to appease the "slower" gamer does not help your cause either due to stagnation , it is counter productive almost because of my stated reasons a few posts above.
It simply does not matter , what I am doing but what you are doing and if you are enjoying the content.
