Power Depleted tokens and Irradiated Garments

As a mage, I got a Power Depleted Chest token last night.

It was my understanding that these tokens were added to help classes complete their set in raid. When I got to the vendor, to my surprise, the mage set is not available. All we are offered is the warlock and healer set.

This looks like a bug. If it’s not, why leave mages out? Now I have guildies mad at me because it went to waste basically. I haven’t thrown the token away, hoping for a fix as this doesn’t make any sense.

How is the Wizard’s Attire not a mage set?

it was stated the irradiated set would not be buyable with tokens on aggrends twitter. the Irridiated set is a bonus drop from bosses only.
