I'm sure that clanless ppl will fight for AI if there was any interest.
The fun isn't here anymore, ai fief are defended by a pub, no organization, no tactic, few players, ticket waster, shity gear (even if better than before), all this things are a big malus in motivation and there is no bonus.
This is more fun to play crpg battle or siege and you win something.
Last battle i made for AI, we were 15 defenders against a full roster, it was a joke, we did what we could but it's no fun to be slaughter.
