I only have one set, I had to pay real dollars for mine just to compete...
On the highly unlikely event that NF do take back every primordial talisman in existence they certainly won't be refunding real money. That said I would be happy to be refunded in a similar monetary value with ingame stuff, ironite, souls etc
But even that won't happen, what ever they do or don't do it will be even in a sense for all.
I'd say it would be more likely another counter talisman would be introduced like the Valor talisman, hell risky putting them on a toon against primordials though.
While I can see everyone's point of view and don't disagree with any of it, it does get quite draining with all the negativity around here these days.
It shouldn't surprise anyone that NF Devs are staying right away from the anger and frustration shown in this thread...
We should all just chill out it's just a game at the end of the day, the older the argument gets the further it will slip from our minds and be replaced with next big thing...
