Power would be a major issue. You may also wonder why we don't have M134 Mini-Guns mounted on our Humvvees all the time. Thats because after about 6000 rounds the power goes out and you need to put in a new battery. Now imagine how fast it would take for a Directed Energy Weapon to run out of batteries. Secondly cost. It would be more cost effective for the UNSC to produce 5000 MA5Cs as opposed to a few hundred Splasers for the same price.
