Was Marked added to the game recently? And is marked actually the invisible taunt on the mythic events? If so, is that why my jtr team's cool downs weren't reducing like I was expecting them to on tier 3 of the mythic pieces and plans?
Marked is just another word for Taunt. The prevailing thinking was that we wanted clear language for "debuff taunt" versus "buff taunt". We only actually ironed this out due to Revan and all the thinking we had to do around him. In that regard, the invisible taunt in mythic events is not marked per se. They're all "taunt". The invisible one is just there to spread out damage since I have no other way of preventing the AI from dog-piling on one unit and destroying it out of the gate. The mythic effect shouldn't have any interaction with JTR that I am aware of. What are you seeing?
