Just a bit of a rant...
Just because you own a mic, please do not feel obligated to use it. If you do not think something is important enough to type, then you should not say it just because you only have to push one button. 30% of the time, people on mics are helpful/hilarious, especially on levels where I am dead a lot like Assault, but the rest of the time they are just yelling "OMG BS!" or spamming in other ways. I do not mind if you are having a conversation with someone, but otherwise please be mindful of imposing your voice on everyone else.
Side note: If your mic sounds crappy and other people tell you it sounds crappy, please do not continue to use it. I understand if you need to test it out to see if it is getting better, but listening to your feedback at the max volume level is brutal.
