1) How often are you forced to go toe-to-toe as a stealth character? I've noticed quite a few scripted encounters or dungeon triggers in my current playthrough, and I don't exactly know how you'd get around those as a stealth character.
2) Is it possible (i.e. not extremely difficult) to avoid smithing and be viable? My idea of a stealth character is one that almost never takes a direct hit, don't know if this is possible with current game mechanics.
3) If you are forced to go toe-to-toe in some situations, how do you survive as a stealth character? As a warrior fully decked out in improved dragon armor I take some mega-hits at higher levels, it seems like you would just be one-shotted wearing light armor. I'm not opposed to using alteration on my playthough, just curious if it would be absolutely necessary.
