Am I too weak? [KCD2]

Hi there,

I really ask myself if I am too weak. I tried to level my strength and skills as much as I could. I fought with some guys which offered to fight, I bought some lessons with money and I am on main level 15 now, strength is on 17, sword is around 16 I guess. I am in Kuttenberg now. Just tried to help that silver mining guy with killing some Sigismund peeps in his fort in Kuttenberg. I had to reload 3 times, because they killed me that quick. I wear a good amount of armour, but it seems that I am still to weak. And that is just normal mode.

Does anyone have any tips or does anyone have the same issues?
