You see, you all say that the DMR needs to be nerfed, but none of you even consider upping the range of the ARs to compete with the other weapons?
For one: The Assault Rifles have far more competition, as the majority of the power weapons in the game (and even other pesky weapons/combos such as the EMP-headshot or, more notably the Boltshot) all function effectively in close-mid ranges, where the ARs are ONLY capable of fighting. Long range CANNOT be achieved with an assault rifle, but the marksman rifles CAN be used in CQB (and in CQB can still win against ARs due to fast kill-speeds from external sources (such as the infamous grenade+one shot, or melee-headshot). the ARs must compete with the two shotguns, the three melee weapons, the explosive weapons (all three launchers, the light launchers), the boltshot, the SAW, the laser are in optimal range for grenades AND can be taken down fairly easy in their own territory by their primary competition, the marksman rifles. All of this competition, and yet the main thing they are supposed to beat can still pretty easily take them out anyway. If that’s the case, why bring a weapon that can’t work at every range, suffers from more competition and terrible magazine-kill efficiency, when the kill-speed between the two weapons is so hilariously close? You basically get given an extra 5% chance of winning in CQB for the price of being the underdog of every other weapon in the game, save one.
So while you’re arguing about the marksman rifles all being imbalanced, you seem to be forgetting that theres three other spawn weapons which are even worse overall and are in more need of improvement than the balance of the marksman rifles, who have far less competition, can be used at any range except for extreme long ranges (where there only competition is the Sniper weapons, which means that they can only be outranged by three weapons), and have insta-kill capability one unshielded targets, which are very frequent in the Halo 4 matchmaking, with the invention of more ingenious ways of keeping the enemy team without shield for a significant time.
ARs need to be buffed to make them a fair choice over the omnipotent marksman rifles, this can either be done by increasing their effective range so that they can compete and outmatch the marksman weapons at higher ranges, or a flat damage increase, which in turn would make over 80% of the power weapons significantly worse, and a number useless unless camping around corners or sneaking up on people (which the AR could do then anyway). it’s either that, or nerf ALL the marksman weapons, which would in turn make the bridge between power weapon and spawn weapon higher, and make it even more difficult to come back after loss of power weapons. It’s better to balance to focus on three spawning weapons instead of two, and frankly, it’s pretty damn obvious that the ARs aren’t widely used in comparison to the marksman weapons, you don’t even need telemetry, just look at the loadouts of 10 people you play with, are they carrying an automatic weapon? No, they use a marksman rifle (usually a light rifle, DMR or BR) and bring along a Boltshot or Plasma Pistol (usually on vehicle maps). You would expect assault rifles to be used 50% of the time as a primary, you could possible drop that to 40% (as there are 3 ARs and 4 MRs), but even then, currently it’s nowhere near that mark, and I assure you that the number difference cannot be put down to coincidence.
Focus on balancing the ARs before you go whining about how your precious BR/carbine is outmatched (barely) by the DMR, AR users have to deal with that while also having to deal with being outmatched by nearly every other weapon in the game.
