Well if you think the lasers are overpowered i can give you details in what it is capable:
-area denial for infantry
-medium-long range support

not capable:
-CQB fights
-assaulting objectives

In my eyes its mainly a squad weapon to support your guys against people who are on medium-long distance. You can aswell defend a objective as long you have a good and wide view in the area where hostile troops need to proceed. However a laser rifle is not capable in taking a objective cause its just not good enough to fight people up close to a objective. Thats where AR guys hop in and go for the hack. What you guys mainly are getting upset is when 1 laser rifle gets into a very good overview spot and basically camps it like no tomorrow on ambush (my speciality). This is a legit tactic cause on ambush you are supposed to get as many kills as possible and dont die to much. And you guys forget the fact that a AR kills up close much quicker then a laser rifle. And shotguns have the potential of 1 hit kills. The AR is a jack of all trades. You get what you pay for. It doesnt shine in any special situation but it is a decent allround weapon. The damage is fine on it cause when you get up close you basically force the laser rifle guy to use his sidearm which is high likely to be inferior to your assault rifle. And i highly doubt that you will see tons of lasers in the future. Simply due to the fact when a n00b picks up this weapon he does terrible with it. To be good with it you must have these things:

-situational awareness
-good positioning
-good aim (cause you need to be aible to keep the beam on the target)
-squad support who helps you to defend your camp spot on ambush

Yes i can get 30-0 on ambush simply cause nobody is actually bothered to take me out. Before the maps became smaller i had massive problems with snipers who hunt me down. And whats so hard to pick up a laser rifle by yourself and trying to fight back? Its basically then the same situation with AR vs AR. The guy with the better reflexes and aim will win. And its not really difficult to find the laser rifle user. Just look from where the bright green beam is coming.

Because ppl are fraking idiots, they see themselves getting demolished by a LR user so they decide eeww i want to try that. NVM the reason ppl get slammed by LR is because they move around open space for too long. All you have to do is learn to find objects to put b/w you and a LR and they are worthless. Then close the gap. Too much open space to cover to close the gap, have you squad provide covering fire till you can, tactics do help. The reason ppl think the LR is so beastly is because most FPSers play out in the open like morons never thinking or worrying about cover until a sniper rings their bell. People just need to adjust, once they learn to think about the possible threats to get from point A to point B they wont find any gun OP.
