I think making kills mostly worthless is about the only way to get the people to focus more on teamwork which is what Brink is about

It doesn´t encourage it, it´s absolutely mandatory if you want to get anywhere in the game. It´s pretty clear that, unless your main task is to defend a spot, you WILL lose if you don´t work together in a senseful manner.
What´s wrong with the HUD for you? Looks fine to me, all the info I need.
The thing I don´t get is that reviews describe the game as complex or sometimes even complicated...honestly, what the fuck? It´s just a normal objective-based teamshooter, what´s complicated about that? People like that must think Deus Ex is a work of witchcraft :D
Rage on the other hand...looks boring. SO boring. 7 hrs of mindless shooting. Again. Thanks but no thanks.
