Screw Yapyap

Went into ranked 2v2s hoping to have a good time. What ensued was 2 Yapyap players turtling in their home base the entire game. They had a shield and cloaking gen, and for troops they had a scarab, reavers, and blisterbacks. They sat inside the shield for 1 hour and 40 minutes while i tried to bust open the base. The few times i did manage to do it they just popped Please dont shoot me and every leader power like the cowards they were. My teammate was useless and barely did anything. Eventualy i had to quit due to things i had to do in real life. So my question is: Why is the sh*t allowed? Why isnt there a hero limit for 1 team? Why do people who do this think theyre good?
