Should have called them out sooner and removed them a lot sooner. Idc if you do not feel well, someone died in your family, pool is on fire, power is going out etc . . . (Have heard each of these one time or another) if you queue for something knowing full well that you will not be able to perform then in my eyes you are scum as my old man would say.

Shit happens, but do not force a group to deal with it, leave without having the group to try a carry your dead weight through the content cause you might be having a bad day.
