I have a similar situation. I have bought precursor, equip it and started to collect mats for legendary, but few months after I stopped playing that character. I’m now in that kind of situation that all that’s keeps me continue play GW2 its to make legendary, but I don’t want to do it on the character I don’t play much. The idea of buying new precursor makes me depressed!!! So “Un-soulbonding” device can be very helpful.
