i think its nice not hearing 100 people yelling and screaming and playing their shitty music through mumble. Just tell your friends to get on teamspeak or ventrilo if you need to talk to them.
I also think it is nice that mumble if not there during loading..... 9 out of 10 times it is complete bullshit that is being said anyway.
If the community would have been more mature I would have kept mumble running.... but my faith in the few people always disturbing the public order is fading.
