wetwillie.. just do a CrossServer Trade.. with that i mean:
Someone from a other server ( like Wintersebb ) will put 5 characters under you ( just mules no real vassals that you need to lvl and stuff ) and you put 5 chars under him in WE. Do the same in a other server and then you got 10 vassals.. you only need 1 character under you then, just search here on solclaim for a spare mule or ask ur friends for one
the 12th and last vassal will be ur chain vassal, and you wont need leadership trained anymore after that.. and then you can put those 4 ( or 6 dunno how much it cost ) skill creds in a other skill
