Relics not being destroyed would lead to your bag being full of relics that you swap out, somewhat like talents.

This is from the q&a (last point on front page).

I have a suggestion about this, hear me out:

What if jewelcrafters (or engineers or blacksmiths or any crafting profession) could craft relic extractors (every profession for another kind of relic)? With these, Relics could be swapped without being destroyed which'll be handy for min-maxers and a consistent income for crafters throughout the expansion. I personally would like to be able to use Relics according to the needs of an encounter (pure ST, pure aoe, mix of both, pure utility). This will be like inscription tomes.

What do you guys think?
