Here's the perfect example of a typical pub match for me:

Honestly, how is it that there are so very many pus5ies out there that seem content to let their team go down in flames or stand by and watch as their buddy gets raped in the ass? At one point, we had 6 (SIX!!!) snipers in our base, shooting down the hallway towards C. Thanks, douchebags, you're a big f-ing help. Things were just about even until it got to 280 tickets, but only because I (and I alone) was taking objectives. At that point, I decided to stop taking objectives. Sure enough, we got capped out in about 30 seconds. For the next 10 minutes, they lost 13 tickets, mostly to my MAV. We lost 280. Shocking.

Why do I care about winning? Why bother? Why not just drive my tank behind enemy lines, hide, dick around, get my kills, and never go near an objective? Why not snipe on Rush Attacking? Why even try at all? Isn't my precious KDR more important than ANYTHING else? Won't I look like a real big shot with such "great" stats? Won't people think I'm the greatest player ever? It sure seems so.
With the new scoring system, BF3 is an utter joke. Congratulations, DICE, on giving the CoD crowd what they wanted...and fu@ked the BF vets without providing the anal lube. Whee.

[Rant over...for now.]
