Do you mean you want mana or some reagent system for magic, or something else?
This has already been discussed.
We weren't there for the discussions about the decision to remove mana and go to a cooldown-based system, but I can't imagine that such a big design decision was taken lightly and without a lot of arguing.
Sure, but I still don't see what the difference is.
Next update might shed some light about what they have in mind.
