It seemed like the action was following the hunter and paladin a lot more, and it was pretty rare for the commentators to mention him outside of necrotic stacks. But you're probably right because it's hard for a healer to position well if his team isn't also positioning well.
having played paladin for as long as I have, it is easy to say if I'm not playing with players that position well I get destroyed by control. If I'm playing with people that constantly fall back and follow me when I call to move to different pillars it becomes really hard to lose. Their team definitely realizes how important paladin positioning is and worked together as a team really well to make sure he didn't get caught in endless CC chains.
