It is never a smart idea to xtal on drop EBs. They do not optimize your chances of success. I was once in a clan where the lowest plunder contributer had 11 actions and got 1 out of the 7 drops.
I for 1 have had a bar/pot drop for bow. Very nice. In the dbl drop tgls, I have gotten a bar drop of some sort more than not. Wish I could say the same for inferno/aqua...lol
2x and I did it about 5 times. 2 bows dropped and one was #82 and another #69 Very little crowns. Heaps of rings though
