I feel sneak attack damage is too OP in the game. Certain creatures should never be 1 hit kills, such as bosses or dragons. It takes alot of the challenge out of the game. And yeah, I did play a sneak character so I know how easy it is to oneshot mobs, especially with 100 sneak skill + perks + boosted sneak damage + nightingale / DB armor. Mobs can be 1 foot away and not see you.
Yeah, an assassin should have high damage on sneak attacks, but x30?
Thats ten times more than bows and five times more than regular non-dagger weapons. Isn't x15 enough to wipe out most mobs except bosses?
Personally I felt x15 was sufficient. The extra x15 they can give to mages as the pure mage / spells are really lacking. But that is a dfferent discussion
