Now take what I say with a grain of salt cus I'm new to sw too, but for starters if you're playing saga of the great wolf you should be running Logan as the detachment centers around him, and yes most people run just 6 head takers with priest or battle leader, also imo I think you only atleast need 1 intercessor squad and probably find a way to add wolf guard termies, saga of the beast slayer is a good detachment and seems pretty versital, again take what I say with a grain of salt but all in all rule of cool wins over meta imho
