I just lost to a possesed army. I haven't fought that many in 1.3, so was surprised to see them (and surprised to be against chaos instead of eldar!).
I'm aware that 1.3 nerfed them, but they do alot of damage to my BM even when the CL is not around. With a cc race, I found it very hard to make any impact on them at all. My micro was shite as usual, and my BO was all over the place, so that might have explained it.
Any advice that doesn't rely on knowing hes going to get possesed before the game?
(i'll get a replay up, but I'm in a hurry, so i'll get it later)
