If you're on ps3 then we the "Trolling Guardians," open our group for you to join. All you need to do is be able to follow orders. So, if you need a team for a raid feel free to join our clan/group. Furthermore, I don't believe that being mute will have an effect because the way the raid is set up there will be 3 groups of 2 at certain points so communication won't be a problem if one person can't talk. Or even half, as long as they know what they are doing.
