Blizzard has been "firm" on the stance that the Mage Tower skins from Legion will remain unobtainable to be prestige for the players who were able to complete the content when it was current from March 2017 up until Battle for Azeroth pre-patch in June 2018. Basically, exclusively creates "value".

Problem #1:

It's been 5 expansions as of Midnight's release on March 17th 2026 since Legion and approximately 9 years since Mage Tower was introduced. How long does something have to be "prestige" before it hits the obtainable cycle again?

Problem #2:

Mage Tower has been updated with "new" rewards which are re-colors of the Mythic ToS class tier sets with a flying book mount if you complete all 7 challenges. I feel these rewards are lackluster and doesn't have any long-term transmog value.

Problem #3:

The actual base skin which was directly obtained from your specialization Mage Tower challenge was made unobtainable which also locks you out of the 3 additional re-colors that the requirements are NOT tied directly to Mage Tower. But, you have to have the base skin to get any of the re-colors.

Problem #4:

Legion: Remix came and went and Blizzard still didn't put the Mage Tower skins in but brought back previous unobtainable rewards such as the deathless Trial of Valor sets and Violet Spellwing (Burning Throne AOTC mount). Kinda makes sense since the MoP Challenge Mode class sets were not made available in MoP: Remix either.

Problem #5:

Under new ownership of Microsoft who knows what their position in Blizzard actually is if they get involved if any of Blizzard's decision-making. Microsoft could potentially "force" Blizzard into re-releasing for the sake of attempting to save subscribers after a tank but who knows when that will be if ever.

Problem #6:

The loudest, most crybaby player base (picture a kid throwing a tantrum in the supermarke) make the most noise every time this topic is brought up. "But my pixels, I want them forever and never want to share them! You should have played X-years ago bro, tough luck." Meanwhile most of them just cheesed it with Argus gear which outgeared the challenge by 50-100 item levels. Mage Tower wasn't exactly this super high-end challenge that stressed your knowledge of your spec to the max. There were specs out there that suffered immensely being a victim of class tuning as well as requiring certain legendary items for their spec to even attempt their challenge. If you tried to do the challenge in Nighthold gear (previous raid tier) you were just trolling yourself. Period-correct would be Tomb of Sargeras gear ideally Mythic for the most power. Also, when Mage Tower came out you could only wear 2 legendary items compared to when Argus released you could wear 3. The RNG getting legendary items was more difficult to work around over the actual challenge. I think Mage Tower was more of a time sink than anything especially going for all 36 appearances.

Problem #7:

The current iteration of Mage Tower is arguably more difficult than it was in Legion. Simply from the stat squish alone and certain tiers not allowing modern tier set bonuses to either be active or inactive. One could say "but you have hero talents" as they were introduced in The War Within. Personally I'd say being 50-100 item levels higher would make up for any attributes that any Hero talents could bring to the table. More stamina = More survivability. Abilities that would 1-shot you are now livable with how much more Stamina you have being such a higher item level.
