Ok there is just one major thing that is bothering me: even the tiniest enemies are shoving me around like a straw doll. I will elaborate.

There I am in my T-45f power armor wielding my favorite gun (double barrel shotgun) and mirelurk baby comes charging at me, jumps and pushes me

back half a meter, my aim goes nuts, I shoot I miss. Same scenario with a ency wincy radroach. Shoving me around like a nutbasket. Nuts!

Then comes a fight with a deathclaw and the infernal beast charges at me head first and rams me like a bull and it pushes me back half a meter. Ok, that is resonable.

Does anyone know how to fix this?

For hatchlings and roaches you don't need aim if they are close, use bash instead.
