Found one: all WoC list a flat 6+ Ward when you try to combine the Mark of Tzeentch with a shield, which is of course wrong. It does this even on cavalry, who shouldn't be interacting with the Parry rules at all. And it completely overwrites any other ward save. So a wee bit irritating for a Tzeentch player.
[EDIT: Oh, and the entire list is devoid of Stomp/Thunderstomp. (Though interestingly enough, the warshrine does mention that it DOESN'T get it.)]
