im guessing you rely on flesh spells?
No I rely on killing my enemies before they kill me

If you are playing an archer, get Steady Hands and Critical Shot. If you have a large pool of Stamina, you can wipe out a crowd of advancing enemies before they even get close to you.
If you are playing a mage, as soon as you get the Impact destruction perk, you can easily stunlock any enemy. This is way too easy and a bit boring IMO, so I've been trying to use other more creative approaches instead. (In fact, I installed a mod that makes it so you only have a chance to stagger, not 100% of the time.)
If you are playing a warrior, you've got to get right up to enemy spell casters and stagger them with a block to interrupt their spells. This works with 2-handed or sword & shield, but not dual wield, of course.
If you are playing a melee stealth character, you have to sneak up on enemies and backstab them. If you get caught, you have a high chance of getting killed, which in my view is the best part of the stealth gameplay.
