For Horde 35.46, 7.78 works
i couldnt see jani appears on the zocalo area cause i have jani as my loa shrine in zuldazar,, i had to change it to gonk or pa'ku for it to appear!
Hek hek hek!
Interesting fact, I got the 385 version in heroic op:mech today, and when I turned it in to Jani I got the mythic 415 cape still. So any version seems to turn into a 415 cloak?
