Eh, I'm a bit sceptical about this story. Initially your point was should people without a level 50 be allowed to roll, then it turned into someone saying they'd pass then didn't. Both are pretty different points.

If they said they would pass beforehand then didn't, then it is a reportable offence, the dev team have already stated this.

However it is irrelevant whether they were level 50 or not. Greed is greed. Is it fair that someone could lose a piece they need on their main to someone who is level 1? No, not really. But that's the price you pay for running the content on an alt class. If this healer was only there for the WHM wand then quite frankly I just don't understand at all why they would switch to SCH.
