Had a nice long reply typed out but the page timed out on me and i lost it all. XD

So short version, Armor skills got an interesting upgrade potentially turning Worlds into the most mix set friendly MH game and potentially justifying the idea of general use armor(no exclusively BM/Gunner armor). Armor skills have levels(Attack has 7 levels, Fire Resist has 3, Fire Attack has 5) and levels stack(Lv.1 attack on Anja Helm and Waist equals total of Attack Lv.2).

Attack armor skill seems to increase attack by 3 * weapon mod(which are back) per level, at least for the first 2 levels. Decimals of 5+ round up. Decimals of 4 or less round down

Fire Ressist increases fire resist by 6 per level(again, at least for the first 2 levels).

Because of the changes to Armor skills, Jewels might be more effective per slot; they might also be harder to craft and slots might be less common.

Weapons also have bonuses: Gs reduced incoming physical damage while HBG reduced incoming elemental damage. Whether it's based on melee vs. range, weapon type or materials they are crafted from are unknown.
