I'm level 56 and even on master difficulty I don't really take damage from anything save an elder/ancient/revered dragon. I'm in Dragonscale armor (not improved) and no health enchantments. I only have damage enchantments because I enjoy playing my archer with the mindset of "if I stay hidden, I kill everything. But if they see me, I'm dead" which is how it was up until around level 50. I used to be able to take everything out in one shot with a sneak attack unless I was discovered and a Deathlord could 1-2 shot me. But now, even if I'm hit from a Dearthlord I only lose maybe 5% of my health.
Anyone have any ideas about what I should do? I would give up the dragonscale armor, but I like the look of it too much hehe. Or should I wait until 1.9 comes out and see if legendary difficulty helps me out?
