Summoning dreadsteed for first time you mean?
That was great Fighting off waves of demons while maintaing ritual, that created feeling of beeing true warlock. Our magic is dangerous (waves of other demons trying to eat your face) but it is badass
Edit:
As i still have ritual items in bank i went to dire maul to try doing it, and to my suprise blizz fixed it, its still possible to go through whole event and summon dreadsteed
(it was broken after removal of soulshards as items, as ritual required them to be continnued)
