They answered one of my eight questions.
Q. If every specialization is intended to take their 31-point talent, why is it not baseline at the level you could acquire it?
A. Those talents are a good “brass ring” to work towards. They often change your character pretty dramatically when you get them, so it’s a fun moment. There is definitely an interesting philosophical discussion about talent trees and how many talents should be mandatory vs. optional. Some players would like a model where everything is on equal footing with everything else. Others want to make sure there are some safe decisions so that they don’t have to do tons of theory-crafting research every time they talent their character. We are trying to shoot for something in the middle where we have some expectation for how a particular spec will play (for example, we don’t want to have to develop and support the non-Chaos Bolt Destruction rotation) but players can still decide if say Blitz is something their Arms warrior will use or not.
