I wholeheartedly agree with everything, save for the point about vore being useless in a fight, specifically at higher levels. Devouring your enemies does indeed seem very inefficient at lower levels, before you have managed to accrue a critical mass of feats, assuming that you have multiple attacks to grapple with, otherwise, it's just absolute trash. Then you can essentially take down a 200+ health enemy with a single turn of action, lock them away in a tummy, and unless they manage to cast a spell and teleport out, or actually have a light slashing weapon that can deal enough damage to cut their way out, they will slowly but surely sizzle away without much they can do.<br/><br/>That's something else the VSRD is a little prickly on, as it states in one place that the stomach AC is 10 + bonuses, and another place states the more balanced 15 + bonuses.<br/><br/>There is always the possibility of letting your players come up with homebrewed vorish archetypes, though, that does of course bring in another massive variable in terms of balancing.
