I don't really see the problem. While there are of course better options, it's still level 60 gear in a level 63 dungeon. If they know how to play the class reasonably, they actually should be okay.
I don't think people usually really care or think too hard about giving a comm. Especially in alliance raids where everything's messy. I usually don't even notice what others are doing, because I'm too busy with my own role and mechanics. Even if I died and got a raise I usually don't remember who's the one who resurrected me at the end. If nobody exceptionally stood out with a special feat, like a sole surviver saving us from a wipe, I either give my comm to someone who wrote something in chat or because I liked the name or the outfit or whatever.
