Have you noticed that mages are getting weaker?
In Morrowind 3 you could recall and levitate....
In Oblivion you could use mysticism... and craft spells...
In Skyrim? No mysticism... no levitation... no intelligence... no willpower...no recall... and maybe no invisibility or spellmaking? Mages are becoming diluted and weak. No mage in his or her right mind would dare forget lore so... profound! What do you think and is there anything else that is being lost to those of with the gift?
I think you are right. And the loss of those spells is directly tied to the desire of Devs to make their dungeons and encounters more difficult by hamstringing and gimping certain character abilities.
That said, Mages never were overpowered, unless you made a science of manipulating the system AND a Master Wizard should have overwhelming powers, end of story, whiners to the contrary be confined to Oblivion. :swear:
