Yakedo, the boss in crimson fields that everyone DESPISES farming, does not have a loot chest. You have to complete 75% of a dungeon just to actually be able to kill him ONCE per run, and even then, he has a chance of dropping just gold and a random garbage housing item, seed, or reagent which is just a waste of time and it's infuriating. Yakedo really needs a chest, or at least make it so we don't have to beat 75% of the dungeon to fight him once. The reason he needs a chest so bad is because he's one of the main bosses in the game that drops insignia gear for stitching. How does he NOT have a chest yet? PLEASE add this to the game!
If not a chest for Yakedo, at least let us summon him more than once per instance. Ditto the boss in Crimson Fields.
Another group of bosses that NEED chests is the lot from Aquila. I mean the final bosses, like Hades, Zeus & Poseidon. Getting to them takes forever just for a chance at gear (that never seems to drop).
