I'm gonna call BS on this...and I have a good reason.

I go 93-1 with 2 caps and 25 defends on Nuketown Dom. All my defends but 4 were from my scorestreaks. My 2 caps were B off the spawn, and having to turn back and get C because nobody on my team captured it. I didn't touch a flag in the second round, yet my team ended up winning 200-45
If you truly got 103 kills in a game, chances are your teammates would have played the objective. I'd love to see some evidence of this loss
