[Notice] Big Foot Glitch Abuse

About the bigfoot being different thing, I've heard that if you fight it normally, when it gets knocked back (?) it's invulnerable for a little while (I wouldn't know, all my non-ultimate 4th job attacks freeze). Would ranged classes still be able to keep it pinned to the wall without a freezer/stunner? If not, it would be great to promote getting classes with freeze and uninterruptible stun to help with bigfoot.
