Twitch, nice to see you are alive and well. Hope things are going well for you.
The rumor (and again this is just that until next week) is that all of their units will be stubborn. The biggest problem (aside from stupid points costs) that they had in last book being viable in 8th revolved around their inability to last in cc. They got 2 rounds of shooting then they just got bulldozed in cc by anything with ranks. If they are all stubborn and or have a viable rank and file core unit option then an msu/mmu setup may be viable.
They also didn't rally have the gear to deal with the proliferation of high toughness monsters. I suspect the treeman options will be a more cost effective counter that they were before.
Having both dark and light magic if it is true won't hurt them any either.
