It was before my time, but I still hear nostalgic stories about how TeamSpeak was once the voice communication service of choice for MMO gamers. Barring a few potential holdouts -- who I must assume are raiding from nondescript shacks in the mountains of Montana -- there's been a very clear sea change that has placed Ventrilo quite comfortably at the top of the heap. If you raid, chances are you have Vent.
Like its predecessors, though, Vent has competitors of its own vying to overthrow the current king of speech. Perhaps the one getting the most attention right now is Mumble, which boasts low latency, clear sound, and the pseudo-celebrity endorsements of more than a few WoW Insider staffers.
Personally, my guild started using Mumble a few months ago and hasn't looked back. Now, this is partly because one of my officers pimps it out like she's getting paid, but mostly because so many of the guildies just plain think it's better. We've run into some problems -- mainly with installation or getting the not-always-intuitive client to work properly -- but for better or worse, it looks like we've been transformed into a Mumble guild. We've even started requesting that puggies download it before raids, promising them that they'll never again want to return to Ventrilo.
So, have you tried Mumble yet, either of your own volition or due to peer (to peer) pressure? Did you feel like there were benefits, or did you find yourself missing Vent? Do you think it will ever become as ubiquitous as Vent or will it eventually fade into obscurity? Most importantly, what will you Vent loyalists do the next time you enter a raid and the leader sends you their Mumble info?
