Mini Tons in WP seem to not die ?

Don't use holy to kill them: problem solved.

Even without using Holy, they still weren't dying for me today in my Roulette for Mythology. They just reached 0 HP and continued to wail on us until we were overrun with them and died. Even the large adds bolted in at full speed on us once. The whole run felt wrong though since I was taking considerably more damage than I normally do on trash as a tank. There's a bit more wrong to just say "don't stun" and expect things to go well.

So it's a known bug, good (?) to know.
Yeah happened to me too the other day using Holy. It was particularly bad because it was my first time ever Holy-ing that fight and so I felt it was me who screwed up things someway <.<
