So for as long as the stats have been known for the SoB I have been trying to find a list in which they belong. For 6 points they seem a bit pricey for their stats. I do not proxy so I had to wait to get them from L&L before I used them. After some play testing, I became a little sad because they never seemed to do me proud compared to the 6 points they replaced. Yesterday I decided to modify my eMadrak list by dropping the longriders and horthol to open 12 points. I decided to maximize the number of bodies because that's how eMadrak likes to work, so I added the SoBs and some kriel warriors and 2 cabers.
I was fortunate enough to play this list against a terminus list. All of a sudden my SoBs were just flying through his banes. My fenns went up the center and the SoB were not far behind and slightly off to the side. I assalted (sp?) from the side and sprayed 3-4 of the banes and luckily they all died. As the game went on the SoB survived due to massive meat shielding and on feat turn the butchered many more models. I think I may have found a decent list for them to play in mainly because they are only medium bases unlike the cav. They can move more freely through my lines causing havoc where need be.
Granted I only played 2 times in this configuration but I think the SoB have finally made it into a list on their own merits. Best spray so far is 8 models killed with an additional 5 due to feat. It really seems like he is the most valuable of the three but the other two can maul heavies.
Let me know about your SoB usage to see what else they can be used in.
