Big Foot Poison Intended?

However, if they make it a boss status monster, wouldn't that make it immune to poison, stun, freeze, doom, etc?
Or did you ment they wouldnt flag it as a boss but would actually keep it a ''normal'' monster with all the likes of a boss except its immunities?

I meant that they would still be vulnerable to the effects that can immobilize it, but the effects that do % based damage would heal it.

Why else would you see blue numbers when you ID/FD it? That's most likely the glitch they were talking about. They probably programmed it to heal with % based attacks (like ID and FD), but it didn't work and still allowed ID/FD/Poison to kill it.
