If you want to make enemies, try to change something.
How they will be toned down is through armour and different perks.
So with level cap 21 there will remain only 4 perks, where on 3 level you can take perk as toughness or awareness. So only 3 will remain ...
I think we need a new attribute for the armours, reusing something like AC or DR directly isn’t too good. But this attribute would then minus off from the crit chance.
One thing I must agree is about "nerf instant kills". Is not rare anymore like in the begining. Is common now and yes, is annoying.But please, do not involve the whole criticals effects table.
Instant kills rare in the beginning? Dude, you probably haven't see how "rare" were instantkills in the beginning (1st, 2nd session)...
