To me laser weapons seem a bit neglected. The only time I use them is when starting a new game and I don't have plasma weapons. Though compared to rifles, they really should have better accuracy. A real life laser weapon should be more accurate than something where a projectile is launched. It's not affected by wind, and the elements as projectiles are. Also they seem like they are under powered. In regards to accuracy of weapon due to troops being unfamiliar with them, XCOM in real life obviously would versly train their soldiers to operate laser weapons
Just look at the military today. I do like the idea of limited ammo shots to a laser weapon. Power has to come from somewhere, so it makes sense that power would deplete. Perhaps having "Power cells" which contain like 8 shots or something. And force people to bring a few power cells per person. That would be a lot more realistic to real life laser weapons. Maybe there can be depleting "Power Cells", and then there can ALSO be a Replenishing Cell which would require Elerium? That would make sense within the game.
