I agree with OP and others. PC version is lacking. 
So to sum this up a little.
-Fix the no sound in maps.
-Optional 1 key does it all feature.
-Bring back the chatbox (no need to hide it). Options to change VOIP.
-People want more options to change the controls of the game and setup options.
It seems developers want to make everything easy for us PC gamers. But by implementing these features, you made it even harder for the PC gamers to love/like these games. For one thing because it feels dumbed down. These features are great for gamepad players. And I for one am not playing with a gamepad on the PC and don’t know people who do.
Mouse and keyboard gives me so much more freedom of control. Only to be taken away by 1 button does it all feature. Please look at ET:QW and give us that freedom back.
Look at ET:QW under the server browser and please copy and paste in Brink. I even don’t care if you don’t change the colour of the browser only that it is added into Brink because it has all we need. And also please add everything that is seen under options button in ET:QW? This will make alot of PC gamers happy.
