US Pc gamer showed a screenshot of Reavers dropped in the middle of a base

I disagree. How many of us actually use reavers as an anti-building siege unit? More often than not we use them as counters to swarms of small units (e.g. marines/zerglings/hydralisks).

The thing I can't understand is how Raynor can talk to Zeratul, because obviously the latter don't have ears. Unless the psionics also work on soundwaves... haha

    In the build we were shown at the Press Tour, there are two main uses of the Queen: Against Terran or Protoss she will stay in the bases you occupy, and build the defences as well as creep. The 1x1 tile Swarm Clutches (that could be 2x2 in next build according to Dustin) are very powerful in tight formations together with Shreikers, albeit quite costly. For a mirror fight against the Zerg, she can be an excellent offensive unit, not unlike a Hero. Using the Deep Tunnel ability to teleport straight into your opponent base and create toxic creep under his workers, or lay swarm clutches on his creep are interesting ways to use your Queen. On the other hand, it might turn out to be a bug, and the release version of StarCraft 2 might only allow tunnelling to friendly buildings, and forcing any "Offensive-Queen"-user to work with Nydus Worms.
