Reduce 2h damage by like 20%
No, overkill if all your other suggestions take place.
Tbh this part of my suggestion would be easier to reason about if there were known numbers for all weapons of all tiers.
So far I've seen 2h hammers do about 2.5x damage of any 1h weapon I've seen. Maybe just my luck. But even with +1AP to weapon damage skills 2.5x more damage looks like too much of an advantage. In general, I think about ~2x more damage would be ok for this option. Maybe it's specific to certain weapon types and just 2h hammers need the nerf.
Warfare skills that are aoe and apply status effects should have a negative damage modifier instead of the extremely high positive they do now. E.g. crippling strike/battering ram should do like 80% weapon damage. The fact that they have AOE, extra damage, low AP cost, apply status effects and in case of battering ram are great for mobility is ridiculous.
Skills should never have negative damage modifiers, mage spells don't deal less damage than wand attacks, archer skills don't deal less damage than arrow shots. Increasing the AP cost is enough in this case.
Actually quite a few skills in mage and ranger trees would do same or even less damage than bow, staff or dw wand attack if they have aoe or high utility. Plus crippling strike has insanely high damage modifier anyway even compared to other warfare skills. Both of these skills have AoE, CC and battering ram is a mobility skill which is also quite cheap. They don't deserve high damage modifiers. Exact numbers are debatable.
