I changed the guild chat server from Ventrilo to Mumble tonight as a test. So far I like it a lot better. The response rate is killer, the sound quality is very high, and it’s able to be customized to allow me to use it as we would Skype for real time chatting during arenas. You can set all the threshold levels for when it picks up your voice, etc. All in all, I’m pretty pleased with it. This isn’t something we’re 100% locked into. Typefrag gives me the ability to convert back to a Ventrilo server or even to a TeamSpeak server for the same price with no additional cost for switching.
