You have got to be joking. 9 is the least melee-friendly of the four new fluxes. 9 is why everyone started coming on pet jobs in the first place. 8 can be done with a mix of melee (for little turtles) and mages (the bosses); 10 is a mess no matter what; and 11 could be done with just melees (and a small amount of luck - and no, I'm not referring to the ~75% chance of a brew dropping to someone in 11 thanks to the sheer number of regular skeletons).
Also, good luck pulling the boss as the first mob in 9 without somehow having all the others join it. If you've got a video of someone pulling that off, I'd like to see it, because I'm not sure it's possible.
