I preferred real 2v2s, until my partners started to cry about honour leaving me to fight 1v2. I even had a guy on friendlist with whom I played a lot who just abandoned me to fight 1v2, because he doesn't want "to be toxic" against those who just heavied me with full hp out of execution or Resurrection-taunted.
Now, I just treat 2v2s as fighting two players one by one with occasional random heavy thrown at me from the side that finishes me.
