I've seen alot of people suggest that it should just be a feat people can take, the problem there is what if the ability is more powerful then a single feat or talent should give you? This monster only has one or two special abilities as opposed to the dozens that the players have. It stands the reason it's going to be more powerful then the standard player ability. I wouldn't want to have to limit the special combat manuevers that specialized monsters could do into only things that are weak enough that they could be feats for PCs.
