Personally I consider it a failure if my players can predict my BBEGsLord Zack said:That's a very good point. But I'm kinda worried that they're losing stuff like create undead and persistant image that are useful out side of combat. And it's one thing to say that the DM can just make it up, but players tend to get annoyed if DM make stuff up willy nilly. What's the difference between making up an attack method mid combat because you feel the moinster should have it and having a monster create an illusion of itself that that the PCs will spend resources fighting or whatever? Not much to me.
