But they
can track the MG who delayed them 5 mins and got 15 kills....
Also, how the hell do you pull off a 5-min delay with only 2 kills?
Yes, they can, but then they're only tracking kills, not the REAL benefit to the team -- the delay.
As for how you pull of a 5-minute delay with only 2 kills, consider the following scenario.
German MG42 is set up at the rearmost sandbags in the Group HQ on Odessa. He's got a full view of the long approach towards the far left-hand side (left from the German perspective, anyway). This is a common path for Russian troops to take, and he knows it. The MG is defending along with two riflemen, and one STG44 assault trooper. One rifleman is at the MG's side. The other rifleman is in the corner of the building with the columns. The STG is set up in the lower sandbags looking onto the rubble pile. (I think you know where I mean)
The Russians send three troops down the approach to take the HQ. the MG opens up and kills one of them outright. One russian soldier runs to avoid the MG fire, and dives by the rubble pile, where the MG can't hit him. But the Rifleman in the building with columns picks him off. The last Russian hits the dirt and belly crawls into the cap zone by the sandbags. The STG trooper cooks a nade and blows him up. All this took about 1:15 off the clock.
15 seconds later, the same Russian crew respawns, this time with another player backing them up. Again, the MG opens up and kills one trooper, while winging another. Just as the MG's about to fire another burst, his accompanying rifleman picks off the wounded man. The other two players sneak to the sandbags again, but a German at the far side who's defending the tower approach to the HQ sees them and kills them with his G43. And we've got 2:30 left on the clock now.
Figuring that the Russians won't try exactly the same trick again, the riflman by the MG moves down to where the STG is, and the STG moves over to cover the other approach to the square, where the statues are. This time, the Russians start running down the usual approach, and two bursts of MG fire makes one of them dive for cover, figuring he can pick off that pesky MG from long range. The other three head down the alleyway, which takes a bit longer than the other approach, but has better cover. As they are about to exit the alleyway, the STG kills two of them, and one of the other two riflemen kills the last. 5 minutes are up, and our MGer has a grand total of 2 points.
On the other hand, he managed to kill two troopers, and keep the rest of the Russians busy trying to avoid him, which put them in perfect positions for his teammates to kill them. What's more, he made the Russians waste more time by taking a longer route away from his MG fire, which both ran out the clock and funneled the troops into a kill zone for his teammates.
All told, I'd rather have that guy on my team than the guy who's simply playing to pump his own points.
