I was talking to someone with the carby mitts, and he said he needed 2 parties of 70+ to take this bad boy down.. not sure but i think level 75 might be a little low.
No I'd agree he is 75...maybe 75-77ish. With a PT of 67-71 we were able to take this guy down. The only reason you'd need more is due to the Troat Stab and Everyone's Grudge attack. An alliance of 2 PTs basically murders this guy. Expect deaths though, it will happen. Especially since he isnt the only Tonberry there, clear the room first then pop him :)
