Tbh, Hunger isn't really lacking in the intelligence department - when it comes to raw stats at least. He has nearly as much Int as he has Wits despite the former being a much rarer stat, and Wis isn't lagging behind all too much either. Plus he has Gisena and Adorie in his corner, who are no slouches in that respect either.
This doesn't mean we can just forget mental stats altogether, but by this point making good choices isn't a question of whether recognizes a fork in his path, but what he wants to follow through on. No amount of 'wisdom' can help you if you really want to charge that Armament are unwilling to compromise on things. Which is not necessarily a bad thing if he has the power and/or luck to back that up.
Though I am curious what other Blood Advancements are gated behind Exalted Spirit...
