If the Protean's main selling point makes it a poor fit on account of it being
a. either too difficult to guess becasue it cannot be accurately depicted without spoiling the game; or
b. too easy to guess if depicted accurately
that doesn't make pointing that out a poor argument. It makes the Protean a poor fit.
We never see anything clearly indicating constant shapeshifting (or even occasional shapeshifting), but we do see things staying constant (rough size, the eyes, having an umbrealla-supporting appendage, having a mouth-equivalent something-something, all with basically unchanging positions…) which tells us that… Constant shapeshifting is going on?
You're frustrated over people asking "why a creature that is constant shapeshifting incarnate never seem to do that"? I find that baffling, myself. The shapeshifting is the entire reason why the Protean is a better candidate than most other epic bull**** creatures.Yeah, I should just stop because we're just rehashing the same things over and over at this point. I just get a little frustrated by arguments that misrepresent the Protean's powers or essentially ask "If the MITD is a Protean, why hasn't Rich shown us the most defining and distinctive characteristic of that species, which he is trying to keep a secret?"
