Maybe the pope shouldn’t take hatred because of dejure claims in consideration. Right now every HREmperor gets excommunicated because he owns so much of the papal state. Even the most pious HREmperors.
Also if the Emperor gives away these lands these lands should be split. Right now the pope gets vast lands in Italy becausr the duke of tuscany is huge. The pope shouldn’t get land from Spoleto to Milano but only Spoleto.
I think the pope's use of excommunications due to dejure claims and his appetite for new land should be restricted to ambitions and/or envious popes. It would lessen the excommunication spam and would truly differentiate between various popes, currently they and their actions still feel rather samey. I want memorable popes, be they of the truly pious and zealous or the greedy and power hungry variant.
