People poo pooed and tut tutted the idea of a permadeath server for 10+ years with all the same excuses - with the mythology being perceived lack of interest - and yet, its the most populated server when its up.
This is why the separation of game spaces is needed. It refutes the "when you get what you want, it affects me negatively" mythology. The reality is the regular servers are still up and the regular game is as playable as it was before the PD server happened.
If the counter argument is going to be: "But Chai, the other servers are extremely low popultion when the PD server is up" then the response is going to be "yes, that clearly shows a large portion of the DDO population does not share your opinion on PD."
