Guild Wars 2

Is there any way to get these put back into rewards for killing Mordrem?

They said at the end of the event they did not plan to reuse that currency.

I was hoping they could rethink that i still have some in my inventory and was trying for the Selfless Potion,Now i have no chance.

There’s always a chance the potion will come back again through other means, doesn’t have to be that one currency.
