Got it in Mentor Roulette yesterday.
We wiped for 1 hour and disbanded.
DPS just was low and healers were OOM at about 20-30%
And new people can't upgrade to 310 to make it faster because verity shop is locked behind this trial.

I'll just instaquit it every time till they nerf it.
Not going to sacrifice more of my time because someone don't know how to balance story mode.
