Fight with a dagger and you will gain exp for one handed weapons, specifically pierce, but you still effect your overall combat prowess, so let's stick with dagger say you leveled all the way too 100 only using a dagger now your gunna be a rude boy with a dagger but if your in a tight spot with a spear your gunna do allright and you'll probably do even better better if you have an axe, why, because of similarities in the fighting styles, to be level 100 in blade and be 0 in blunt boggles the mind. So I think a more in-depth and realistic approach would be to have every combat skill effect every other one. The values represent the modifiers your charcter has when weilding a set weapon, the main weapon class skill decides your base skill with a qeapon then your sub skill modifies that. This should be based of a percentage, so sticking with dagger, you gain 100% in the direct main skill, one handed, and sub skill, pierce and 50% in the connected sub skills. 30% in two handed skills, with 15% in all other skills, being gain due mainly to nerve and exsperience not so much skill. This way you level one handed all the way with a dagger and you'll be level 100 at onehanded and + 100 at pierce, you'd be level 50 at your other sub skills, because there very similar to your specialty, level 30 in two hand and it sub skills, as they are reasonably similar but but different enough to leave alot to be learnt, then only level 15 in pole arms and marksman, as they are more divergent that the straight handed skills. The reverse should happen if you level pole arm or marksman, they only effect them selves greatly and leave you at low stat for all other main skills. I believe this balances out the range boost this combat types have, making you need to specialise more in them and not have them dragged up high enough to be viable and visavursa, this amount of stacking is reasonable as if your level 100 in 1handed and 2handed you'd still only be default level 30 in Mm and Pa. If you went with 100 in 2 handed and pole arms you be level 45 in 1handed and 30 in Mm.
This gives a more believable rounded set of weapons values, with enough variation to promote character development.
You still have fewer skills but now you have sub skills to help redefine the blended skills and this way they are more realistically represented. This would work well with the blending of running and jumping, an athletic person would be a good alrounder but may specialise in a sub skill of swimming within athletics.
