I don't know if there is any possibility to add the option of being able to do Eureka and Bozja's questlines again without having to use an alt (this goes especially for Bozja, since it's gated behind a whole Alliance Raids questline and, on top of that, one that involves raids that take a lot of time to get the queue to pop).

While Eureka questline was okay enough and, having elemental level maxed, getting it re-done shouldn't take much, what I really liked was Bozja questline, the lore behind it and the quite unique solo duty we get at the early stages.

Maybe there are technical issues that get in the way of getting them to NG+ but if CB3 could get it done, it would be really wonderful.
