In combat area (pvp and pve) to remove such damage factors as tracking speed of turret (explosion velocity for missile) and velocity of target.
This mechanics not makes combat better but less usable, more ridiculous and laggy. No one use it in combat, I mean no player who through seconds last battle calculate in mind compositions of this factors. Morever it’s impossible to implement due to many factors including natture of game itself (clients-server-clients intercommunication).
It is to stay only with size of weapon (small-middle-large) so damage will be mainly dependent on it. And target’ signature will be slightly interract it.
