A couple of thoughts of mine for the extra souls:
1) Use souls to restore health, magicka, stamina. Say, one soul restores one of the three to max. Three restores all three, you get the picture. Make this a greater power, so it can only be done once a day. Maybe even less often.
2) Use souls to gain levels. Now now, before you crazy - hear me out. Some prerequisites for using dragon souls to level up:
- Have completed the main story-line.
- Be at least level 50.
- Cost 100+ souls.
Yes I know there is an aspect of this that means your character is "indestructible"....but is it already not? I mean I play on Master difficulty and still 1-2 shot most enemies.
Levels at 50+ are less of an experience of leveling up, and more a "jesus christ alteration, LEVEL UP ALREADY - so I can put my perk into something that has nothing to do with alteration >.>" experience. Because of that, I feel like 2 is pretty justified, especially noting its other requirements.
