What should happen to ECD?

Remove it. Hasn't served a purpose for a number of years, and frankly master builder should go as well. If someone can come up with a good rework of it, I'd love to hear that idea but as it stands both mean nothing.

In my opinion, I think the role of ECD should be to inspire more players to build.

Not everyone is a master builder immediately, but the ECD could show examples and techniques. For example how to add more depth or improve a build. i also think they could encourage more players by doing various build showcasing on the forum, if the build is worthy.

From what I have read, because the role is specifically directed towards master builders, and the lack of them, its understandable that the role is quite limited and not used very much. However, if we give the ECD a wider audience to manage, I feel this would change the perspective of the ECD's purpose in game or on the forum.

I still think holding it vacant for time being is the best option.
If someone comes along that has both the time AND skill to take the reigns, the position will still be available to them. Leave it marked VACANT so that if someone thinks they have what it takes to take the position, they know it's available and ready to be filled.

There is nothing wrong with holding vacant spots.  Sometimes it shows you're trying to grow and gives you room to grow to.

Completely agree with this.

Wait, holy shit mibbzz I actually agree with you for once! 

Is there any need for you to be passive-agressive towards everyone. Yes you've made your points, and so have I, but i've decided to stop trying to be like this towards other admins, simply because it doesn't do anyone any good. Instead of being like "I actually agree with you for once", just say your points or else you're just gonna cause more drama.
