I wonder if someone know if Black lion backpack retur?
I'm not sure which one you mean, but there's very, very few things in this game which are released once and then never seen again, so chances are it will come back sooner or later. It's hard to predict with gem store items though, there's not really any pattern to it so if you're waiting for a specific item you just have to keep checking.
