Need Advice - Replacing player.
So here's my issue, I currently have a player in my guild who isn't exactly bad, he's average if anything. He's doing mediocre healing though. 20 to 25k HPS below the other two healers, and has a huge issue with the English Language, not only is English not his second language, nor his third, it's his fourth. So far we haven't had that big of an issue, but we're not really doing heroic kills either where there's more chaos and more on the spot calls. I'm worried one of these times when he has to do something major or specific to save the raid from a wipe, he won't understand what I said in the heat of the moment.
But more importantly, I found another druid that's just flat out way better. Double if not tripling his heals and has a lot more experience. As well doesn't have the issue of a language barrier.
What's the best way to replace the current druid after the raid week is done?
