This was an interesting testimonial. Here’s mine:
Depending on your class, spec, gear, and race (looking at Tauren healers with that sweet Stomp), there were certain challenges that could be considered easier by the time Antorus dropped. This was quite variable however, especially with titan forging being a huge influence from when the tower first opened. Many specs required specific legendaries to be considered viable, and it was a total roll of the dice whether you got them. Cold Heart was bis for FDK, and absolutely could have helped with the frost challenge. Except it never dropped for me. The reality is that even with set gear, many players had to hodge podge whatever legendaries they had and adapt their builds around what they had.
In general, Agatha was probably the easiest DPS boss. Vengeance DH basically cheesed the tank challenge by virtue of their glide. Affliction Warlocks could flat out skip a phase on the twins.
By comparison, this current tower has been much simpler due to gear cheesing (stacking gems in old gear and busted trinkets like seed pod), and class kits being able to overwhelmingly handle the tower mechanics. During SL, you could still use of enchants on gear like Mark of the Hidden Satyr and Crusader. I decided to take my FDK into the tower a couple weeks back just to see what it was like, and I steamrolled in two attempts with Aberrus tier gear whose bonus was disabled.
The Legion tower took a lot of time and practice, and in general was more difficult than the current version. And while the Legion tower did get easier over time, it was still difficult. Hence, only about 1/3 of players got a single challenge skin, and only about 1/10 got all challenge appearances for all specs of that class (about the same number have done the current tower).
While I can appreciate how easy the tower was for you specifically, the numbers tell a different story. In essence, if they were all gimmes, everybody would have got em.
But since people are getting hung up on semantics: the tower in both cases is the most challenging content available for solo play- visions in BFA and Torghast are a joke by comparison.
And let’s say for the sake of argument they were totally easy cheesy and everyone playing Legion got them. The purpose of the rewards per the devs was to act as a badge of honor for anybody who did them at the time. In essence, they function identically to the game’s ecosystem as AOTC mounts.
