Only thing that really annoys me so far (aside from the constant crashing and escort missions) is the "rest until healed" mechanic. It'd be nice if there was a downside to doing it or there was something preventing you from resting multiple times in a row. Otherwise, it's really easy to just rest until your magicka and health are maxed out after every single fight.
...speaking of magicka, is there an enchantment or something similar that gives you constant magicka regen? It would certainly be more convenient and possibly OP than just resting over and over. If not, I'd at least like to know of some vendors that sell more than one or two "restore magicka" potions at a time.
