trust me. Sitting on the 60s or more, is a pain. All the bandits, draugrs etc are leveled, and if you have skyrim monster mod and several new world space mods like me, plus Skyrim redone and uncapper, you are gonna have a hard time dealing with these leveled guys. I find that i need 10+ melee hits to kill a marauder bandit, and a marauder bandit with a steel crossbow simply 2hit me to death(same with town guards). I did have high levels on onehanded, blocking and light armor but i feel the game is significantly harder after level 50 or 60 on master compared to levels 20-30 on master

You have a hard time because your game is heavily modded. If you played vanilla, most enemies wouldn't level past 50, so you'd be practically a god.
