I miss being able to stock up on potions of mana in a shop somewhere. In Morrowind it seems like I have to roam the countryside looking for different ingredients for something that will maybe restore 10 points. I'm used to just about every other RPG I've played where mana recharging potions/hypos are pretty easy to come by.
One problem I'm having is keeping my mana/magicka/whatever recharged. Hey, I'm trying to do a mage-like class in morrowind since it sounds like there are a lot of possibilities there.
