What exactly would a warzone need for you to describe it as "pug friendly"?
I consider something pug friendly if it allows for individuals to make contributions without requiring communication with allies. I think you can achieve this on Alderaan and Void Star(you can cap nodes/harass enemies and contribute). No, you won't win by yourself, but it would be absurb if you could 1 v 8.
Now, Huttball, I will agree with you on. Huttball isn't pug friendly. It requires communication to set up passes and provide an offense and defense. And god forbid you don't have a healer on your team. The team who happens to have a healer will win almost any pug v pug battle. If your allies don't cooperate, then you can't contribute to the battle. A premade with voice chat has an absurd advantage in huttball because they can plan and talk to each other.
