Thank you everyone for your feedback.
Due to your feedback, we decided to not go ahead with the faster Balance Test map, and we'll wait until we know if there is a balance issue before we make a move in this area.
However, we will be exploring tweaks to the Swarm Host in the Void beta, so depending on how that works out, bringing that over to HotS can also be a future option for us.
Thank you again, and we'll continue to keep a close eye on the state of the game.
