Rule of Thumb: If your KDA is negative DO NOT FLAME YOUR TEAM
Even if they are not playing the best you trying to tell your team how to play with a 3/6/4 score is not going to help because if you really want the game to go better try to go 3/3/3 next time or 1/0/0 that's the fastest way to make your games go better. and if you know this and just need to vent let your team know so they know to not take you seriously
