Salganos: you seem to be speaking of having a sweet spot along the length of the weapon, whereas I'm pretty sure Jack_Merchantson was speaking of a sweet area in the swing arc. Plagurizing
Crazed Rabbit in order to make things clear, this is the type you are speaking of:
And this is the type he was speaking of, that he suggested was relevant to the current thread:
I also think the second type is important to the success of the game, by restricting the effectiveness of players with a good system and connection hitting at the very start of the animation before their opponent has any chance to react; whereas the first type you were speaking of would be a nice realism enhancing feature, though not quite as critical for the game mechanics.
It hasn't been implemented in any way yet from what I can tell; I tested on the combat dummies in 0.701 and hitting at any part of the swing still does the same damage, even if the sword is practically already touching the dummy before starting, or the sword just nicks it at the very end of the swing. On the other hand stab sweet spots were fixed recently, from up too close or too far away little damage is dealt.
