You know you can report them if they did that
IF what you're saying is true regarding monopolizing the instance, which I've never seen. In fact, I've seen the exact opposite. I've seen the other side bad mouthing BA groups, thinking they prevent PW from spawning, saying "I wish they all fail" in shout chat (yet they were the first to run to kill Ovni and the support NM lol).
And regarding the portals, when the premades say they want it, those who say "it's my right to take a portal" stay quiet all the time till the portal spawn and stabilizes. Then they take it and shout "it's my right". Why not say so from the start? I've never seen the premades claim the portals harass anyone who wanted to participate before the portals spawn, since
nobody talks till they snipe it lol.
There is also another GM response about that I saw yesterday.
