Ball formation sounds strange for me, more likely you have to have big concave so your units will able to surround or at least get in range of enemy tanks
This actually sounds like a great idea against obsidians, but aurora that may support them kills labs with only 2 shots
Edit: ups, have not read about shield... Well i guess this kind of formation sounds really fun
