While we don’t get a new hero for the game in this update, we can at least welcome “new†heroes into Captain’s Mode as well as some bug fixes. As we ponder on how Drow and Tusk can affect the META game with their inclusion the Tournament Version Captain’s Mode, players who frequently queue Public Matchmaking CM and Team Matchmaking now have something new to try out as three more heroes enter the Latest  Version’s CM — Bristleback, Slark and Skywrath Mage. On the other hand, designers also have something to look forward to, as the Workshop now includes HUD Skin design submissions.
