Paul announced on the 4/17 dev stream that specializations will collapse so when you choose one specialization you cannot choose the other options any more. Personally I like being able to research all specializations so I'm asking for collapsing specializations an option for the game rather than default. I know there are a lot of people that like collapsing specializations as well as people that like being about to research them all. Please make both groups happy and make this an option.
