I never got teleport spell and invisibility spell before mid to late game, and I still haven't gotten my sneak to 5 on even my rogue character. Maybe you should let the choice of skills and specializations be based on what you want for your characters, instead of based on min/maxing?
What I want is balanced combat without having to make arbitrary rules for myself to gimp my characters on my end.
If they had spent more time doing that instead of Crafting or other stuff like Charm games - maybe.
At the current state a lot of skill sets are clearly too damn good at low level. Badly paced, and high AP costing abilities are not as attractive as lower level ones.
