@Warhead - Nice catch, so no real need to up the Unique level seeing it is basically 1 for 0-5950 points, 2 for 6000-8950, etc.
I also liked the old FREE cards for Eldar. I thought it was a cool touch, but that's water long under the bridge...I can remember losing that argument in version 1.1
@Malleus - Unique has already been added to the Guild Bikers co., Saim-Hann WILD RIDERS (c'mon, doesn't anyone else think the name is wrong?), and IG Rough Riders.
I don't think the issue with the Guild Bikers Company is that they get much free, it is simply that they are a bit too good for the points as individual detachments, and when you then roll them up into one, massively hard to break company they become 'unpleasant'. Now, all armies have the odd "excellent value for the points" units and I'm sure no one begrudges the Squat player a Guild Biker co., but multiples are not so nice.
I agree with Scream that the Squats don't have great alternative Assault troops (though don't underestimate the re-roll 1's on the Infantry), but then they aren't meant to are they? Squats have always been take and hold type guys, and late game objective grabs are by grinding all opposition to paste then waddling in with the troops rather than a gung ho charge in to HtH.
