Would be nice to have an additional tier option to queue for HM EV/KP. In my dream world, I'd like yet another tier option for SM Denova as well.
At the moment, I would never even consider running Denova in a PUG. You couldn't make the rewards high enough for me to even attempt it. It's way too coordination dependent and not conducive at all to PUGs.
Most people on the PTS felt the same way, so they took it out as a possibility.
