Took several days before I finally got the whole Marauders set (still works with 5+royal), but now it's there
Tried to gamble for the chest with no luck and then today when doing T6 rifts I got a nice drop stream (15+ uniques, 5 green in 1 hour!) and there it was
Now I need to gear up on emeralds and start hunting for Tasker and Theo for that 40-50% speed increase for pets/sentries...
Still need to figure out what part to keep and which to toss to raise the low damage (Considering Natalyas Slayer + ring or helmet for those noce +250 dex, +7% crit and +20 max discipline)...
Best part is that my son Benjamin also have his set and we now destroy in T1-T3 together
