Change can be fun, sometimes it works sometime it does not. One thing for sure is if you don't try something new and just talk it to death you will never really know. For better competition here is my suggestion. Add a function to the controls that would :
1. allow you to switch your icon to user id which the other team could see.
2. allow direct vox to the player your fighting.
I think this would spice up the game. If you did a merge, punched the button and not only knew you were facing Shawk, but was able to talk to him as you fought, I am willing to bet the respect and the willingness to help each others game play would improve dramatically!
