Sounds like he's calling out TF2 and CoD.

And I know so many people that are of the "Multiplayer = Bad" mindset, mostly because they played CoD or Halo once for an hour and got their asses kicked.

I feel like people are taking his conversation out of context. He's not implying that they are tailoring the game to bad players but trying to make the game as non-exploitable as possible.

There are still ways to balance without totally nerfing it...

Grenade Launchers are heavy and slow but should still do a lot of damage. It should take an eternity to reload and only allow you to carry like 5 shells. Soldiers can only give themselves ammo so many times and if reload times are really slow it should help deter a person from going too crazy with it.
