I don't really get to play against
O&G often, but I've seen other armies have success by sending a light unit way ahead and and drawing out as many fanatics as he can and just let them wreck the enemy's front lines with their random movement. I figure 2 units of
MY with a LOT of luck, will be able to take out both squigs and draw out the fanatics. I reasoned this because it appears to me that they would be likely to leave an opening in the front line for the squig to move through, because nobody would want the squigs to run in to the back of their line and go crazy just from a high random movement roll.
I dont know if you like to run a prophetess, I personally do, and it appears that a prophetess with the lore of heaven, assuming she gets wind blast, could really do some damage do an O&G enemy. you could blow a mangler squig into one of their units, or a fanatic once it's been deployed. I do not think it would cause the massive number attacks that they each inflict, but I'm not sure as those units are... unique. But d6 S3 hits would still likely be sufficient to take out a fanatic, and combining that with a few bowmen shots you could definitely take out a squig.
