Agreed... but we did beat them.

BTW, Grim is talking about taking position in the water for the standoff in Death Toll. Hunters cannot pounce when standing in the water, making it really hard to form an effective group coordinated assault on the survivors. Our opponent team exploited this by camping way back in the water.
Honestly, I think that exploit is too new for people to expect some sort of "neutrality agreement". It's sort of natural for people to demonstrate their elite knowledge of the game to everyone, and eventually everyone agrees "yeah it's lame" and no one does it anymore. The melee door on the second level of No Mercy is a good example.
So, clearly it sucks, and let's agree to not use that strategy in the future. It's game-killing enough that I expect Valve to fix it soon, anyway.
