First thing,
I know Elemental is not MOM... Moving on...
Currently when you design your Sovereing, i wouldn't see why you wouldn't want to pick all the spellsbooks?
I would of liked for Elemental to perhaps have a tiered system for spellbooks (a la mom). Or something that depending on how many points you invest in Earth or Fire magic (at character creation) you would have access to more or less spells, and maybe research them faster.
At this point, I feel my Sovereign is the Jack of all "Magics". I'd like to see the game impose some kind of restrictions to "multiclass" sovereign.
Or are all powerful tank mages in again? 
Because of how MOM presented spellbooks and talent picks (both with the potential of being extremely effect (spellbooks as much as talents) it offered so much customization as to strategy and overall approach to end game. I find it's too easy to design a all around sovereign that can learn all the magic that exists. Should there be any type of limitations to this?
Someone had suggested that maybe, you get the basic spell book. And that later spell levels require X amount of shards of the appropriate Element?
And this point, there is not point in NOT picking all spellbook, as well as there being no "consequences" in doing so.
Also, unlike MOM, there aren't enough 'good' talents taht would lead you to believe that you could do more fighter oriented Sovereign. Almost feels like, they shouldn't even allow you to pick the spellbooks or not. Just have them all by default.
Anyone thinking along these lines?
Feedback plz. 
Thanks,
