Just no, stop trying dude, you look like an idiot saying this. Not only is there a limit of 2 nades, but there is also the ability for a person to time something and throw in the right direction. Vs where as using a gun all you have to do is aim in the right direction.
Not to mention the fact that without nades, 2v1s are stupid. Without nades there are no variables at all. If you are out gunned and don't have nades, 95% of the time you going to die. If you have nades...you could kill one, or both of them faster then they can kill you, but it takes some skill to get the double or even kill one before you die.
If you don't play with nades, friendly fire should atleast be turned on. That way it isnt just a bunch of run-n-gun.
