Re: Changing the direction of knockback???
Thinking about it, besides the risk to the person firing, it also occurs to me that the odds of the target taking any damage from the knickfore is pretty slim. There aren't often going to be vertical surfaces between the shooter and the target (since if there were, the target would be shielded), so that would keep the KF damage to a minimum.
As Knockback damage is one of the biggest benefits of knocking back an opponent, this is probably enough of a limitation to counter the advantages of knocking someone to be closer to you.
I think I like the +/-0 option.
Thanks.
