So you just gain a 4% overall difference, meaning even at 800 Attack, would only net you an additional ~30 Attack, averaged over time. But occasionally, you will have a lot less attack on the abilities and weapon skills that matter, WSs loaded with Warcry or Blood Rage, self-skillchaining with Sekkanoki and closing with a Warrior's Charge WS. That alone would probably be enough to make up for the entire 4% Attack increase, not to mention Warcry and Blood Rage last enough to get several WS in.

If you are using Warrior's Charge for WS's then I am actually fairly sure you don't know what you are doing. Warrior's Charge gives better damage output if used to gain tp faster to do an additional WS not using it during a WS and getting a few extra damage from it.
