I've been repeatedly bitchslapped by the warbuggy thing. The Ork player deploys the battlewagons side by side, with AV14 facing forwards, and then on either side, a warbuggy squadron. The first turn, everything moves forwards, and the warbuggies move outwards and further forwards slightly. The only lines of sight you can get from anywhere on the front two thirds of the board are against AV14 or warbuggies. The second turn, the buggies move further out and further sideways, again blocking all your flanking units (it's surprisingly hard to take out a squadron of three vehicles). By that point it's too late, and you still have to deal with the buggies before all your wasted flanking units can get back in the fight.
