Guild Wars 2

Am I doing something wrong or is there no way to change the stats on ascended accessories?
I’ve used the anthology of heroes to change armour and weapons but it doesnt work on rings/trinkets .
I’ve got plenty of ascended rings I’d like to change as they are useless to me atm is this possible?

If it’s not possible is there a reason behind it? Like would it make things unfair or break markets etc etc

No, you can’t do it. If you don’t need them, just salvage them. You only can change stats of the new bloodstone ones.

If you’d be able to change the stats of ascended trinkets that way, it would completely nullify every other way to obtain ascended trinkets. It would make half of what the laurel, guild accomodation and fractal relics vendors sell redundant. ANet is not going to do something like that. I believe this is also the reason why we can’t craft ascended trinkets, since that would have the same result.
