Bah, i gues i\'m too tired and have not enough patience to understan S-Plankton way of thinking. But i want to add somethink to this topic. I would like to explain how skill system has been solved in Project Entropia (evil) game. It is mostly crappy commercial product, but even crappy games have few good ideas.
There was numerous skills and these was used when you was trying to perform some action. Eg, if you wanted to fight with sword, skills which ws used was eg accuracy, damage inflicting, and some other. I dont remmeber well.
But it isn\'t the point to write which skills was in PE, but to describe the pattern.
In PS if you train light armor a lot and start using medium, you will have no bonuses at all. But the fact is, using light armnor you dont train only this, but some other skills which are used if you equip medium armor and heavy armor.
In effect if you was training with use light armor only, when you equip heavy or medium armor, you will have some knowledge in using these too, but not as great as with light armor.
That is why i propose to make from all three armor skills, more basic skills which would be used in different importance when we have equiped eighter light, medium or heavy armor. Skills like dodge, skill to avoid being hit in weak parts and so on.
