This reminds me of when I played SWOTR. I played a commando and they were if I recall, the only dps that didn't have a silence. Of course, commandos wanted one because silencing an enemy can be very helpful to the group. People that didn't play commandos said, "You don't need one, just have someone else silence. They didn't give commando one for a reason." Well long story short, they ended up giving commandos a silence. Did anything change in group dynamics? Were different classes excluded in raiding content because commandos could now silence? No. Nothing changed except for the fact that groups had another person that could silence. So basically, there's no point in saying drg shouldn't get one because all it would do is make group content have another person of any class be able to help interrupt attacks.
