Personally i bypass or one-shot almost everything using nothing but sneak and a dagger. Sometimes i resort to hit n run sneak attacks using archery and they all die before they can even find me. Got lots of stamina and can sneak-roll-sprint pretty much non-stop. For my play style, restoration is a bit overrated.
and how would u fight dragons? always running away and drink pots till your stomach explodes?
In my opinion, without dragons Healspells would be non-essential, but with...
just think about a 2h fighter (only meele) impossible to kill a dragon without 1000 healpots with you...
or did i miss something?
edit: i dont want to make healing better then it is, i just cant figure out how to live without it
