Ascended gear stats
Just make Legendary Armor
Been There, Done That & Will do it again…except maybe world completion.
Weapon and armor item nomenclature is dictated by the mats that are used to make their inscriptions and insignias. If you want berzerker’s you need to buy/collect Vials of Powerful Blood; if you want to craft valkyrie then you need Vicious Fangs.
I think an item like you’re suggesting could be potentially disruptive to the economy regarding T6 mats. At this moment, Elaborate Totems sell for 19 silver while Vicious Fangs cost 39. In a free market economy these prices are dictated by the supply and demand. An item that would enable someone to craft cleric’s and get valkyrie instead would throw the price balance in the T6 ranges out of proportion in relation to the availability of the items which could have costly after effects in crafting from exotic to ascended as well as impacting the crafting of legendaries.
The only way to counter that would be to price this stat changing stone far above the prices of current transmutation stones so that it would be an item of convience to the user but not so that it could exploit the market. At that point the stat stone may be so expensive that it would be cheaper to just recraft your armor or weapons yourself. The implementation could be very tricky to balance and probably wouldn’t work out for most.
