Mainly a question for HC raiders.
My guild are currently progressing 10m HC two nights a week, then we clear the rest of Siege on normal as a 25m team. Out of 10 people, only 6 of us speak on TS. I know some people don't like speaking or they may just not feel comfortable, but Heroic progression has been very problematic due to people not speaking up. For example, on Sha, our RL asks us to call out who is taking which rift so there's no confusion. Except...there is. The people who don't speak will take a rift but no one knows, so someone else will run to take it...but it's already gone, so people are wasting a lot of time running around for no reason. This is the case for a few other boss mechanics - just confusion all round.
Am I correct in thinking that for HC progression, people should really speak up during important mechanics? I don't expect them to chat if they don't want to, of course, but I wonder if it's holding us back a little. They will type in the chat box if instead of speaking, but it's quite difficult to focus on that as well as the boss itself.
What do you guys think? I mean, apart from flat out asking these people to speak up, is there anything else we can do? The RL is at the stage where he's just frustrated and is considering replacing these people for ones who are willing to speak, but I just want to make sure there's nothing more we can try.
