@CaineHoA: Good points. It's something else I intended to mention. A few montgs ago, I brought dual Aggressors to game night and faced Tarn Mison accompanied by the 2 of the cheapest YT-2400s, each with HLC. My opponent was flying his list "just cause he could" and I was still working on my tournament list. I cleaned up quickly, as one would expect. I don't think the game was really fun for either of us, but that's not to say dual Aggressors should be banned. Instead it means we should have discussed what we were hoping for that evening before setting up squads*. I think that may be the kind of thing the OP was talking about.
*(In reality, my opponent wanted to test it against a meta squad to see how it would go but didn't really expect to win.)
