Here is a summary of suggestions I think would improve the melee system:
1.-Press and hold attack key should hold the melee swing back and attack only on release. Similarly, press and hold block/parry key to hold that ability until release.
2.-Change stamina bar to drain and replenish at a much faster rate. Have sprinting, melee swings, and blocking draw from this bar. This bar could be repositioned in combat mode to show up to the side of the character vertically and somewhat translucent for easier tracking.
3.-Change hit detection to weapon swing arc (in-game confirmed by Jooky)
4.-Add side, and back dash animations that use the same key as sprinting available in combat mode.
5.-Use mouse gesture before pressing attack key to indicate direction of melee swing (similar to Mount & Blade)
(i.e., Quick movement up and then press attack key = overhead attack.)
6.-Change blocking and parrying to use mouse gesture system mentioned above. As a side note, what is the difference between blocking and parrying? Amount of damage deflected?
7.-Tweak animations to better create illusion of momentum. (i.e., heavier weapons = slower swings and makes character step into swing due to momentum of weapon)
8.-Have heavier blunt melee weapons knock down opponents on overhead swings. (ie, Two-handed bludgeoning weapon will knock your ass silly on the ground for a second when overhead attack succesfully lands.)
9.-Some type of reward for quick successive unblocked/parrying melee hits (ie, special attack animation with increased dmg, stamina drain, very short debuff/stun on opponent).
