I had a similar issue last year where my Empyrean went missing (presumed accidentally tossed). I got through to both a GM and SGM concerning this, and they were unable to restore it due to "it conflicting with a quest" or something to that effect simply because I had obtained it via Trial of the Magains. The SGM later told me they are completely unable to restore anything from ToM full stop.

Relics/Mythics/Empyreans get the Augment tag thrown on them automatically even if not augmentted. I noticed when SE introduced Relic +2 armour that when you upgrade via ToM these do not get the Augment tag until you start/complete the Merit augment trial. My question being, why can't SE apply this to Relics, Mythics and Empyreans? Even if they can't, they should at the very least make these weapons exempt from the unable to restore rule.

I've asked SE before, I'm asking again now:
Whats the point in an item restore system when it effectively excludes the most difficult to obtain sets of weapons?
