Does More Features Warrant a Worse Online Community?

This question has been asked by many people who play Modern Warfare 2. At first the vast array of additional features seemed nice. They included things such as Pro Perks, different guns, and various equipment options. However, over time, many gamers have discovered various "exploits" or "cheap methods" of playing the game by combining these new features together to create annoying playing methods (ie using the grenade launcher then getting continual ammo from it by using "One Man Army"). Many people have actually stopped playing this game in order to avoid these annoying people. What should be done about this? Everyone wants more features, but as it seems, it just uncovers more ways to cheat and annoy other people. It actually appears that the better a game is, the worse the online community grows.
