We are actively addressing 2 or your major areas of concern.

We are hoping to update to chat in a way that will greatly ease guild and global communication. In the interim there are many guild changes and improvements that are the core of our 4.2 Update. One of these improvements is a more interactive and accurate guild finder. (PS, 4.2 is releasing in December!)

Sirrian made a committment to look into affixes and trees, and is currently doing so alongside Nimhain. We are re-evaluating how these work and hope to have a solution in game in the near future.
We frequently listen to player feedback, which is why we are actively looking into improving both of these areas of concern.
