So what I am to understand here is that a lot of people wish to opt out of this (not me personally, I'm really excited); however, they are upset that other people will use this. Thus excluding them. This seems to be more a problem with the players than the feature. If you don't want to hear other players then don't use this, but don't cry and complain when other people say things that you don't hear. In short many of you seem to want to prevent those of us who are interested from using this simply because you don't want to use it and also don't want to be left behind. For those of you who have complained about issues from deafness to speaking foreign languages, I say oh well. Disabilities are just that the lack of an ability; if you are unable to use this system because of a disability, then don't. Do you get mad at all your regularly abled friends because they talk to each other near you. On the other hand if you do speak a foreign language, kudos to you, but you seem to do well enough in English to put together a well written post. If you are from France we have the European servers for you; if you are not then consider this the incentive you need to master a second language that you already seem fairly proficient in.
As far as role playing goes I think this will add a whole new dimension to it; especially after reading the warcry review on vivox. I fully look forward to people speaking as their characters would (voice font's should help a lot) instead of constantly using internet acronyms for convenience sake.
