Get rid of the 31 point talent trees. At the heart of an mmoRPG is the talent system. When content runs out, and you have a deep talent system, there is still fun to be had and discovered. As things stand right now, once you find a "rotation" the game play of your toon will never change. It will be the samething over and over for the foreseeable future.
As an example I will give you RIFT. I played waaay more warzones there over 10 months than I did here. They didn't get repetitive because there was always room for me to change and grow. After 1000 warzones here they became unbearable. It literally was the same thing over and over. TSW is an even better example than RIFT of a deep talent system.
Please add your input in the name of making the game better for the future.
