I'm not a fan at all of the new knight factions, though the green wolves look better than the other two yet oddly they are not available in stores.
The lions seem like a clown army and I strongly dislike the painted armor parts on these new falcons. Both armies could have been much nicer if they had uniform soldiers, it could work pretty well for them.
I'll skip these, I tend to only get new knight factions if I can use them.. mostly I got many tournament knights since they could be easily used as a vassal or such.. and plenty of lions that work with the classic lions.
Depending on where my stories go, I might need a reasonable number of medieval soldiers of another faction, but it wont be any of these three.
