Frankly you really shouldn't be at 100 in any skills considering the game isn't even finished.
The only people with 100 skill in anything but running and jumping and maybe wood cutting and pickax.. are people who wasted hours skill training or staying in the world long after the current content.. and a loss of 5% of skills when you have at least 40% more than needed is kind of meaningless in terms of being able to survive. In fact if you go from 100% to 95% and blame skill loss for death then I think you are probably playing over your head by a big margin anyway.
