Reality is that these disruptive players don't give a crap.
All this talk of faith is old news and idealism to them.
They just want their crap and run done with disregard to other ppl. (Old news yup)
After (or even before) 1st wipe due to overzealous DPS or Healer's too busy DEE(r)Psing, I find it best to just leave party and leave them to do their monkey business to themselves.
