In my personal Opinion, the Delivery of Damage is to easy on some platforms... Take a look at what weapons dominate the field, regardless of player...
In order:
Crossbows/Throwing weapons: Basically use them self and anyone half decent can score hits for "massive damage" (loomed siege, 100 dmg)
Archers - Self explaining, but actually not to bad damage wise....
Katana/Weeaboo weapons: Very fast, easy to use - easy damage delivery once your in close combat
2h Weapons (Epic range, partly with silly speed)
-Polearms, 1h and shielders-
You see that the weapons that allow easy damage delivery, are used the most... so I'd mostly agree with the first suggestions point in reducing damage:
Throwing weapon damage reduced by about 20%, but higher in the top end of skill requirement.
Crossbows harshly nerfed by about 20-40% of there current damage output
Overly fast weapons that jump out of balance, nerfed by a good bit (Katana, minus 5-10 cut damage or speed brought in line with others)
Speed reduction on most 2h weapons
Return the game to player skill, not who lands the first lucky hit...
