Yeah I think they changed it too so you get a slot no matter what, plus somebody told me if you're in the faction you get +1 slot (not sure), then you can also have perks that will add on a slot and because the relation is only for adding the next slot you easily end up with 1/2 the stuff available to you. HOWEVER a problem is that all the AI clans also get this (and maybe 1 more slot?) and in later games I can go across the entire middle of the map and barely find any recruit along the way because everything is picked dry by all the AI parties. To ad on, if you lead an army of vassals, they will grab up the recruits as you stop in fiefs but will not donate to the garrison after a siege, so you have a hard time getting garrison fillers.
