Simple question I suppose:
Which Mythic encounters, if any, made use of a specific ability that only a single class could bring?
One of the arguments for the fixed 20-man size of Mythic was that it allowed the designers to create encounters that had special mechanics for a group that largely guaranteed the availability of the right class. In my limited experience, I can’t think of a single fight that couldn’t have been tuned down to be either 10-man or flexible.
Was there one?
