These guys are just great. I don't play them that much, because I usually run quite heavy on beasts and I still prefer Bloodtrackers over this unit. That said, the Woldstalkers has enough RNG, POW and RAT to be a threat. Especially with Mohsar and his Curse of Shadows, these guys can actually take out a heavy 'jack on average rolls. A neat trick is to slam something into a nimble target and zap away.
Anyway, these wolds look cool and they are quite fun to paint. I really like the druid models that Circle has, and the Stoneward is no exception.
