A couple of suggestion and adjustments IMO the game needs.
As others have said akimbo weapons are too powerful. This is a secondary weapon and it should not be better that a submachine gun at close range. IMO you need to add an ADS penalty or make them less accurate. The fact you are holding each gun with one hand alone should impose that accuracy penalty.
Spawn system, enough already said.
Too many twisting pathways on some of the maps (Carbon for one) and none of the perch points in the urban maps like MW and MW2 had, that, if you dared take the chance, you could get to (like the crane on Highrise or Terminal rooftop). This I acknowledge is a tough balancing act as you don't want a snipers paradise but since they don't have the environment to hide in, the urban maps need these to give snipers a chance to be effective.
Weapon choices based strictly on weight not predefined layouts with primary, secondary, etc etc. If I want two claymores at the expense of a secondary weapon or flashbangs, why not, as long it doesn't exceed a weight limit. And the more you carry the slower you run. That's already employed now but based on predefined layouts.
The last is an incentive and thank you to the fans of the franchise that provide material suggestions that get incorporated into the game. A long time ago when I played Rainbow 6, the original developers (Red Storm then Ubisoft) use to take suggestions and incorporate them into the game as well. A couple of mine actually made it into Ghost Recon. The reticule changing colors when you targeted a teammate for one. It was a last minute addition that was not in the beta. I always though it would be cool if the developers, as a thank you to the contributors, would add their names as contributors in the credits.
