Morosini's cat should definitely go. Someone has been reading Norwich too much
The Sarpi event is unbalanced because of the tax value changes. -5 basic tax value is unacceptable and should not be imposed on the AI even in 5% of the games. That BTV is probably trying to represent the problem of the many urban properties that were ending in Church hands by testament, but that clearly cannot be 1/5 of total Venice tax value.
As I see it, it should be a chance to decide the orientation of Venice:
Option A: Asserting independence: Stab +1, BTV +1, Inno +1 Relations, PAP -100, SPA -25, HAB -25, FRA +25, ENG +25, HOL +25
Option B: Compromise: -50D, Relations PAP -25
Option C: Submit to Rome: Stab -1, BTV -1, Inno -1 Relations, PAP +100, SPA +25, HAB +25, FRA -25, ENG -25, HOL -25
In the context of the upcoming 30 YW, countries were taking sides, and Venice was clearly anti-Habsburg, and was able to get Protestant help in their fights against Austria over the issue of Gradisca and the Uskoks, and against Spain in the naval war of Osuna. That is why the relationship changes should be expanded.
Option A makes you innovative, and you are rewarded, while option C makes you narrowminded and you pay for it, but a more just price. You can get out of the choice by paying an idemnity to the Church (option B) and remaining the same.
