I know it serves no purpose, but you took out crouch. There may be no point in doing it, but you feel wierd when unable to do it. I hear its being readded though, so

Its mostly the maps that are the problem though. You added mountains to LowCube. I understand you can take them out with Normal Word Detail Settings but still doesn't the defeat the whole purpose behind low cube? Another thing is the ambience noise you add to your maps, why can't you just leave stuff as it is. You added a very useless and pointless wind noise to lowcube. It does nothing to help the game other then put me in a strange trance while keeping :p. The crowd noise is also another problem. I know I've been complaining since 1.3 about the crowd noise, its not even the fact it you can't hear the charge as well but the fact its just annoying.
Lastly is the fact that you ignore people who say they can't tell when they have the ball. Most people you tell to be shutup and that there is two noises and its not too hard, but where is this other noise? It doesn't exist. People have gone and tested it out with bots and they havn't heard two different noises. You also say the little icon in the middle is enough help, but most people are two busy trying to get open, hammering people away and looking at their radar to even notice the dumb icon. If so many people are saying they have a problem, I'm sure there is one.
I can't think of any closing paragraph other than I hope more dumb changes like these don't happen and the little things are fixed.
