somehow they have been "buffed" constantly in the last 18 months:
glancing chances decreased
Honestly I've always seen this as a nerf to 1-handers. Here's why:
Though they decreased glance chances, they increased the amount of damage that armor absorbed. So less hits glance, but you need more hits to kill someone.
The only time you really glanced was if you had a cut weapon, relatively low strength and you were fighting someone with heavy loomed armor. In those situations cut weapons are as useless now as they were before the change.
What that change really did was reduce the effectiveness of cut weapons against medium armor, which is the most common armor in the game. On medium armor you never glanced anyway, but now you need more hits to kill someone. Not really a buff to 1-handers there.
Unfortunately, pierce and blunt damage types are far superior to cut unless you are fighting someone with no armor. Cut damage only really starts to shine when you are REALLY stacking strength. High cut weapons benefit the most from stacked strength due to them gaining the most from Power strike (due to power strike being a percentage-based increase). 1-handers (who generally have lower str due to shield requirements) also suffer from less of a damage increase from power-strike due to the lower initial damage of their weapons.
It's unfortunate, but after the change you're always better off with a blunt or pierce weapon as a 1-hander than cut.
Here are some examples:
12 str 4 PS 100 wpf armed with military pick (30 pierce) vs 30 armor:
average damage: 24.5
12 str 4 PS 100 wpf armed with military pick (30 pierce) vs 50 armor:
average damage: 15
18 str 6 PS 100 wpf armed with military cleaver (35 cut) vs 30 armor:
average damage: 29.5
18 str 6 PS 100 wpf armed with military cleaver (35 cut) vs 50 armor:
average damage: 17.5
In this example, the pick user is using a weapon that does (5!) less points of damage AND has 2 less points of power strike, but the damage levels aren't far off.
24 str 8 PS 100 wpf armed with steel pick (32 pierce) vs 30 armor:
average damage: 38
24 str 8 PS 100 wpf armed with steel pick (32 pierce) vs 50 armor:
average damage: 27.5
24 str 8 PS 100 wpf armed with military cleaver (35 cut) vs 30 armor:
average damage: 35
24 str 8 PS 100 wpf armed with military cleaver (35 cut) vs 50 armor:
average damage: 21.5
Give him a steel pick and the same exact str values and you see how terrible cut is.
All the armor change did was make your average fight last longer - which is dumb.
