I'm not talking about higher level stuff, I understand that.
I'm talking about getting killed in fights that I should be able to take, but I'm not.
For example: Walking along a path to a town, just a normal path, not in a dungeon. I get ambushed by a lone Imperial. At level 21, my armor is Steel Plate Armor (Superior), Steel Plate Gauntlets (Superior), Steel Plate Boots (Superior), and I did add an Ebony Shield. Altogether, this is an armor rating of 152. I cast Stoneflesh, which adds another 60 to that, so 212. My Health, via leveling up as well as other health bonuses is at 195. The lone Imperial totally owns me because he aggros on me, instead of my follower.
The "mudcrab" method is near impossible, seeing as how even mudcrabs of all things dish out large amounts of damage on me.
I know my stats aren't the best stats in the world, and by no means do I feel like I should be the ultimate tank, but I feel like it's utterly worthless for me to put on Heavy Armor as opposed to unarmored. I feel like I am dying so fast that it makes zero difference.
There are no fights you "should be able to take" only ones you can or cannot take. If your playstyle isn't working the way you want it to, then change it; the game isn't going to bend over backwards (any more than it already does) to accomodate your absurd playstyle. If you want to be able to take a good lot of damage, then kit yourself out to take damage.
