I remember back before patch13 seeing Zealot with a lasgun was a pretty normal occurrence to snipe specials and to deal with shooters when their skills or melee choice wasn’t up for a task.
Problem start at Auric where the density makes using las weapons just weak and a horrible experience. Add to this that melee is constantly around you and the game has a habit of spawning disablers targeted right at you if you spend more than 3 seconds in ads.
Even if you are a real sweatlord with twitch reflexes there is basically no payoff for the playstyle.
