irregularities

Dwigt: Hello MIKlars, I can answer some of your concerns here but please note that this section is more about game mechanics related questions. A lot of fights end with 15: 2, 15: 3 Yes this can be frustrating but there are some explanation behind it. First the matchmaking is not only skill based or based on win rate but it includes a lot of other parameters. Second when a team gets a 2 3 kills advantage they have a great advantage on the enemy team and can start pushing, flanking... more kills will follow.they lead 6: 0 .... Here you go. Communication in the game is very important but unfortunately it doesn't happen in the game much often. You loose one side, the enemy team start capping.. suddenly their heavies are behind you. I destroy one tank and I have 0 points ... I have a photo ...Can you share the photo please or the replay?
Usually if you hit/destroy a tank that is not spotted, let's say you blindshot someone hiding in a bush, you cannot see the damage done or if you got the kill, but it will still count when the battle is finished. 
 I hope I was able to answer some of your questions. 
Let me know if you have anything else you wish to discuss Have a good one!
