4. The dye system

This was a fun idea, and in beta I think we all thought this was amazing. Then we learned that you can't die high level armor. It has been mentioned before in these forums that allowing high level gear to be died could be a boon to the economy, I tend to agree with this sentiment. I understand the technical challenges with such a robust system, a unique texture map for every color variation on new armor that is added to the game, but this was already done on low level armor. The process might take a lot of time and isn't more important than the above items, but I think it worth noting here.

Not even gonna touch housing as SE has made an honest effort to address this even if its perhaps too little, too late.
