I considered making the AMK head to dex/agi, but the only reason I didn't was because I also use it on my BLU, for first spells, I'm a Galka so switching from homam to full damage stat gear ultimately can cost me up to 200 something mp for my first spell x.x Salade has mp on it. so its rather useful. But that's a topic for another forum lol.
I still use Jin from time to time outside of abyssea, I get those random misses where I'll land a 200-500 Hi and I feel like I should redeem myself with trusty Blade: Jin. But yeah like you Langly, Blade: Hi is my favored now.
