While Melee is a class that is intended to get up close and personal, it doesn't really work since you put yourself in much more danger just to get DPS that is outclassed by much safer options. Nothing is stopping you from wearing melee armor while picking up a gun and taking out your foe from a safe distance. Giving these ore swords a beam would not only be a neat reference, but it will reward the player for keeping their damage down while maintaining an aggressive playstyle. As such, I'd find it appropriate if the beams would dissipate for a relatively medium-short distance with a slow attack speed, so that the players can take a breather and maintain pressure whenever they need to fall back or get away, but can't use the beam alone to deal significant damage to enemies. Especially considering the play style to get any results with melee weapons, this change is almost dire for ore swords.
