When this post was started I had in mind the classes that jumped ship. I immediately thought warlocks as they have a similar dark theme and a lot of locks were complaining about their class balance at the launch of legion. Rogues I kinda figured would jump ship, leather wearing, dual wield, agility based class. Didn't expect to see hunters and paladins though, because people are normally very loyal to them especially paladins. It looks like mostly an even distribution of melee classes with the exception of warlocks.
