The new proposed enhancements for Kensai and Frenzied Berzerker give real promise to THF characters. I think it's time to address the weapon speed for greatswords and falchions.
Other threads have addressed the slower animation speed of two handed swords versus mauls and greataxes. There is a clear advantage to non sword based two handed weapons. This decision to not fix these in the past has been purely based on looks for the animation.
As can be seen by hasting or using fighter haste boost, a faster animation is neither a technical issue nor an eyesore. People are used to attacks occurring faster than would seem possible.
It's time for the devs to address this and level the playing field across all weapons of a similar type.
Devs, please look into the attack speed difference and make an adjustment to attack rates to make all THF weapons on par (quarterstaves excepted).
