It's so hard to consistently land light attacks when playing melee (2h/dw/snb). I don't know why is that.. All medium weaves and all heavy weaves always land perfectly without any issues. But most of my light weaves are simply not getting registered on the enemy. In fact i DO light weaves, but they just hit the air instead of the enemy. I am clearly aiming at the target and am within proper range, yet still missing it like half of the times.
It's only in pvp though. When i do pve i never experience this.
