The mass driver from Dust, apart from a few times where CCP did their usual over nerf/buff to it, it was a surprisingly well balanced grenade launcher. Could give it to Light assaults as up high they would be devastating but could be off set like it was in dust by having a low ammo pool and a couple of variants a large raidus low damage one, a mid tier ok damage ok radius and the tiny radius massive splash damage version. A LA up high with it would be effective but prone to sniping, other LA's (1v1s with MD's weren't great unless you had loads of practice) and unless they got a spawn beacon up there they would have to retreat for ammo periodically. Second and also from dust the laser rifle. A good concept but apart from the time they accidentally buffed one version to be godlike quite underused, it did tiny damage at close range and did more damage the further away the target was and did more damage the longer it was fired (continuous fire weapon) with the risk of overheating which would lock the gun forcing a cool down and doing damage to the player firing it. Lastly obvously a joke but this shall demonstrate its raw power.
