These are some things that irk me in 2v2, teammates who:
A. Think they are better than they really are and spout it in the chat.
B. Blame you for their loses even though you are fighting an enemy push on another side of the map.
C. Spam the chat with how they are going to quit and then attack your base or/and refuse to move when you don't surrender right away.
I do get frustrated when players don't surrender when they have 2 or less units with no AT and the enemy has several tanks (which happens) and they are waiting for their Tiger/IS-2/ISU call-in which they think is going to magically win them the game (not with their sub-par skills).
In the above game though I still had most of my army, but he had lost a lot of his (my fault apparently) and wanted me to quit, even though the enemy wasn't in great shape either. So he sends his tank to start attacking my HQ and refuses to move his other units.
In the chat you can see he starts screaming about being double teamed one time when the enemy ran around my maxim at him, but notice I send my maxim over to help, so I don't know why he was crying about it so hard.
Also notice that at the very beginning he pings the enemy on his side's Kubel for me to attack, so I sacrifice starting power on my side, I send a Maxim over to help him, then later when I am getting pushed back, does he send any help? No! He screams at me for being a noob, even though I sacrificed starting cap power because he couldn't beat the first Kubel.
I did make a mistake with the Zis-Gun (I didn't realize I had asked it to attack the Schwer-Panzer HQ), that was bad play on my part.
What frustrates you about 2v2+ teammates?
(Keep individual names out of it, let's not let this develop into a hate thread.)
What do you do to try and help your teammate?
The in-game chat is really sub-par and I use Auto-hot-key to help me micro, so I have to turn it off an on when I want to chat. Which is why there is some gibberish there in the middle.
