The OP is doing the same mistake over and over and over again and is blaming the devs for the OP not understanding the game, even though they got told over and over again.

1. You can't just charge into enemies nilly-willy.
2. Even the lowliest Fuling hits hard.
3. If you don't eat the food the biome has to offer, you're dead. By now that should be lox pie (and yes, they hit even harder) and blood pudding.
4. Food is more important than armor.
5. Food is MORE important than armor.
6. FOOD is MORE important than armor.

I run around the plains in a combo of lvl 3 padded helm, and leggins, with a lvl 2 Fenris chest to offset the speed penalty. Weapons are lvl 3 draugr fang, lvl 3 black metal shield and axe.

Even the dreaded deathsquito is now mostly an annoyance. Single Fulings easily get disposed off.

What you have to watch out for are Lox, Fuling beserkers and whole groups of Fulings. They will kill you quicker then you can think, if you are not prepared.

Food is THE most important item in Valheim. I keep saying that. Are you ignoring it?

Edit: If Fulings two shoot you, you probably at most ate some deer or pig. Good for meadows, even black forest, but not beyond.
