First off, it doesn't really matter who benefits from the trinket more
cheap wow gold, because it's best in slot for both specs. Second, who it benefits more has to do with your raid role, not your spec. It's true that a holy priest is more than likely going to be acting as a raid healer
wow buy gold, but disc priests will occasionally fill that role too, just like holy priests may occasionally tank heal. Because raid roles change from fight to fight
really cheap wow gold, I would encourage you to not be that jerk who tries to make a case for it by waving his spec around.
