Its clumsy wording, but I don't expect to see a lot of examples of the 'problem' in play. The paladin is going to give up almost of all his abilities to exploit the mark in this way, and be very ineffective overall. Or have to blow a lot of feats to be even marginally effective.
While paladin pete and fighter fred are trying to pull shenanigans on this one monster, the other monsters have successfully killed and eaten the rest of the party.
