HOTS is well put based on what the Pro's requested and what Blizzard wanted to see. This was clear in MLG, where I didn't see a single boring match. It's faster, more intense and takes a lot more strategy than just build orders.
Terrans dominated (in numbers), a Zerg won and there was a Protoss in the semi finals. Pretty damn well balanced. Yes, Terran is now as annoying as youtube ads, but so what? It keeps us on our toes.
