I only learned about them bringing back the feast rewards today, and just wanted to drop by to say I feel the exact same disappointment as the OP. I worked hard to earn these during the first 4 seasons of solo feast. Didn't always succeed but that's fine, skill issue.

Since they're already making old exclusive rewards obtainable, when can I get 1.0 rewards? Never I guess? But it's the same thing - an exclusive reward.
