This from a game last week that Kal and I [played. 3000 points Squats vs 3000 points Emperor's Children. The Squats won by the end of turn 3 2-0 (Take and Hold and Blitz). Despite no winning any initiative rolls the Squats were able to roll along the left side and hold the middle and prevent Kal from taking any objectives although he was all over my right flank.
The army points are well balanced. They have good firepower but not over whelming. The free Rhinos really help keep them mobile. I used the Leviathan and 2 Goliath cannons as my WE selection. The Medium sized Guild Bikes were causing Kal all kinds of problems beating back 2 engagements and breaking 2 Chaos squads. Next time I will use the moles to sneak in deeper.
Shawn played Kal to a draw in the second game. He also played Squats. His use of Mole Mortars and Robots was excellent. His army was different where he used the Colosuss and Airship as his WE selection. He has more activations, 12 to the 10 I took. His squads were typically smaller. The sweet spot for the squats is a balance between using M sized and S sized squads.
So the Squats went 1-0-1 for the day against the Emperor's Children.

Squats brought a Warrior unit in Rhinos, a motorbike Guild, a unit of the shooty Gyrocopters, Berserkers in rhinos, a Goliath, and a blimp.

So after a few years of hiatus, I am currently painting up my Squats and am happy to contribute to list testing next year. We're currently reviving the local Epic scene in Berlin, Germany. I tend to get games in at least twice a month. Are there any army lists that prove particularly problematic with this list? In terms of being OP, or UP?
