More harmful attack
 

Currently the only way to kill someone, who doesn't want to be killed, is to get them while they are AFK :(
Imagine your guild/kingdoms is trying to defend some gate, the enemies would just run through your lines and maybe lose 5 HP.
I think if someone is hit, he should be slowed down for some seconds instead of being pushed back that much, so the person who is attacking him can go further attacking.

Also, I think the defense that shields, or karate/swords + hitting the "back" key give, is ways too high. I think instead of taking no damage, the defender just shouldn't be pushed back and have a chance of decreasing the damage dealed, if any.
