not sure if its been touched on yet (haven't had time to read all 9 pages), but I think that each summon will have their own set of skills, maybe not 5, but at least 2-3. The current battle system revolves around combos, and they are not going away in 2.0. With that said, you would think that each summon should be able to do a self combo because, how silly would it look to perform a 3 skill combo you had to spam summon 3 different primals in the span of 20 seconds?

To me at least it would be a lot smoother if each summon had their own unique 3 skill combo.

just my thoughts
