Many times after a dogfight and a win, your ship will be totaled or just scratched up beyond recognition. And sometimes you cant fit that welder ship/drone into your small ships. Perhaps a welder laser would be a good addition. The laser job should be only to do the repair part of a welder. Not adding materials to the block. To make armor blocks mold to the original shape. A welder beam would only be needed to be around 5m to 10m. Main problem with current techniques of repairing ships is slow and prone to leaving minor damage to both ships (welder and small fighter.) Sure you could also make a whole 3x3 of laser but the power drain should be considerable due to the energy needed to fix a block. Lasers as a weapon would prove more fatal during a dogfight due to the speed of the beam compared to a projectile based weapon. That is why I don't think lasers should be a weapon. Plus more weapons would increase the adversity of gameplay during fights.
