Dynamic Melee System For Zerkers

First of, I am a huge fan of KF. 2000 hrs logged lol. One thing that bugged me in the first one though was the lack of control over melee weapons-whenever you clicked, it just executed one of several preprogrammed slashes. Why not have a system where the WASD keys, or mouse movement itself determines the direction of the swing of the melee weapon? This could also set you up for a cool parry system-like being able to time and match a Skrake's chainsaw swing to be able to parry and counter it. Perhaps even light/medium/heavy stances to deal with different zeds, with respective combos :P(although I understand thats taking it a little far). This would definitely add an extra element of skill to the zerker class. Oh-and COMPOUND BOWS. I want to shoot FPS in the head with explosive tipped arrows, then run away as it rages on my squad mates >xD.
