You know what? The 'easy way out' as you call it IS the reason. We are sick of people constantly backing out when things dont go their way, games crashing because the host needs to protect their precious KD, getting teamkilled when close to a high end scorestreak because timmy no-thumbs couldn't watch his fire.
All this impacts our gaming experience, and we pay for all of our setup too. Now, who would you rather cater for, the part of the community who plays honestly, watches their fire and take their beatings on the chin, or the part which throws a hissy fit each time its losing/doesn't want to take a knock to a stupid stat, and cant understand the concept of DONT SHOOT THE GUYS WITH THE GREEN NAMES ABOVE THEM. Your bad habits negatively impact the experiences of others. You evidently are incapable of reaching high streaks, else you'd know full well the annoyance of being TK'd off a swarm, or watching said swarm fly around doing nothing because the enemy quit out, or even worse getting booted back to the lobby because the host just switched off their console in a childish rage.
And btw, its 3 TKs, not 2. If you get kicked after 2 that means you shot someone pretty much straight after you spawned and that counts double. Why? Because you have to be an absolute arse to get a TK then if you aren't trolling.
