"The system might be nice, but there is such a high chance of ruining a good game with it, that I don't want it in Dom2."

I'm against this. Firstly, it replaces attack and protection with six new stats (at least). Secondly, it requires that certain kinds of armor are made arbitarily weak against certain kinds of damage, for example, plate armor being weak against crushing, even though the only real difference between armors is the protection, weight and cost, which the game already models.
Thirdly, there are already differences in the way that different weapons and armors interact, which provide far more flavor for much less complexity.
