Though Grey Knights are nasty in Land Raiders. I played someone a 1500 point game, and all he deployed to start off with were 2 Land Raiders and a Dreadnought. The game ended with my Wraithlord with one remaining wound in combat with one of his deep-striking Terminators, in the centre of the board. And the mission was Take and hold, so no-one won. Sheer madness. Though to be honest, my Uber-Autarch and his 4 Shining Spear bodygaurds were all hacked down by a single Grey Knight.
But I still agree, they look like you need a considerable amount of skill to play well with them.
