It takes more than 1 bad healer or ill healer or new healer etc. To ruin an Orbonne run. Hard to say what the case was with the one healer, I don't always mark a healer's performance based on how smoothly the run is going, but how they have a grip on things. If the group is really pushing it, then healers will struggle, great healers can make bad runs feel smooth because they are carrying people's mistakes, but a healer that can't isn't necessarily the weakest link but can be the first people will point fingers at.

So it is hard to cast a shadow at the healer you had when we don't know what that healer was up against.
