First, you likely used the same spells over and over again. Because something like dispel magic can't be used in most fights anyways. The main difference is the variation in spell load between trash mob fights (95% of battles) and boss fights.
Second, a lot of spells have the same effect anyways. All of the elemental weapon spells were the same other than the visuals in 99% of all fights. Weakness and Affliction are basically the same spell. The appearance of more spells is built on having a lot of different name same game stuff.. I don't mind seeing fewer spells if there is a more generic: enemy can't hit me, I can always hit him, enemy can't move type of spell ather than 2-3 spells to do the same thing. I am not losing any options there.
Third, think about DAO where Walking Bomb and Virulent Walking bomb were 2 different spells, even by DA2 they were one spells with the "Virulent" part being an evolution of the Walking Bomb. You might have evolutions of the spells more than "new" spells.
I am not that worried about this assuming that they have adjusted the total number of spells. Passive aren't on the list.
My main fear are Sustains and if they have to be activated in combat ala DA2 or if they will be always on ala DAO.
