Why is there no Savage tier content for solo players?

[Jeeqbit]

There is not a lot, but your options for hard solo content

• The 3 Bozja duels.
• The 3 Zadnor duels.
• Palace of the Dead.
• Heaven-on-High.
• The Masked Carnivale.

I put the Masked Carnivale there because I recently did it and although I got through most of them quickly, some of them involved practice and progression and I began to appreciate them a lot as a solo endgame content.
