Fairly specific question: there is one non-partied THF in the Aqueducts that shares a spawn, supposedly, with a RNG in the Eba (Fomor NM) room. I am going on 14 kills of the RNG in a row without spawning a single THF, 4-5 subligars, driving me nuts.
Is the THF respawn rate significantly worse than the RNG or am I experiencing some poor statistical "luck"?
