Bonus rolls are an amazing way to get gear when there's other people shooting for the same item as you.
Your opener damage is good because of the shado pan trinket fyi. That trinket is pretty insane during the burst opener. Someone posted graphs of how trinkets perform awhile ago and the shadow pan trinket has the highest burst out there but sadly it's on a long CD so it's a very spiky trinket and does insane damage while it's up but it just takes awhile to come up again. And to that no, using a 502 trinket would not be worth it over the shado pan trinket. Rune is dog poop for rogues for the most part. Bad Juju and shadow pan probably are you're best two to be running with over all.
I was running a normal mode renetaki's/shado pan for awhile and picked up the bad juju to replace shado pan with it. I noticed that my burst opener went down by a decent amount but the over all sustained was a lot better. Kinda sad not hitting those crazy numbers at the start though
