In my experiences I've noticed the gaol mechanic traps (obviously) one healer and one DPS...and oddly enough, as far as I can tell, it's the DPS with the least amount of TP/MP (proportion wise).

I can't confirm this, obviously, but I've noticed when a character is KOd, they always get gaoled upon being raised, where they have low TP. When I see monks going all out with the GL3 they tend to get stuck in gaol, etc.

Anyone wanna try confirming this? Not that it would change any strategy, but just to know more or less what's going on. Maybe it's even the same mana wise with the healers? Who knows :P
