I feel like the current pity system for savage drops is...bad.

Worst case scenario you can be waiting nearly two months to get a leg/chest/weapon which seems a touch excessive and it's not even that unrealistic if you're not running with a static.

Even though your odds of actually getting loot were technically lower, I felt a lot less sour about the pre-ShB system because I at least knew I was guaranteed to get my gear when it decided to drop.

If anything, I think they need to just normalize the number of books required for each item to four instead of "weighting" them based on how much benefit that particular slot provides because the associated fights are more difficult then prior ones anyways.
