I have put most of my drops from the last three days into one screen. I tend to get a lot of the same bosses on multiple occassions. I have had no luck finding most ToI bosses when I have checked this week. Usually I get to the floor and see it dead, or nothing is there except people that are higher level than me trying to camp the same boss lol.
I have finals soon so I probably wont play or update much over the next two weeks. Once I am on break I will be in level mode.
