Dark Barrack.. Empty spots..

Forget everything you've heard till now about the dark barracks. First thing's first, Lava Hound needs to have a few less hit points, more damage per second, increase speed, & and spawn less creatures. Secondly, a Goblin King hero sounds pretty sweet, paired with a new dark barracks troop, Goblin Archer (mov. sp 30, 25dam per sec, 75 hit points, training sp 1min cost 100de). The second empty dark barracks slot would be filled with the Yeti I've been hearing rumors of. That would leave two empty spaces for additions down the road. I'm sure other mathematical problems need to be fixed with the next update, but as a new player this is just my opinion of the road the game should take! What's yours?
