It would be nice if there was an NPC that let your purchase raid gear from raids you have cleared. For example, if you've cleared Second Coil Turn 1, it lets you purchase items from that raid (though if you haven't cleared Turn 2, you can't buy anything that drops from there). In the context of Second Coil drops, this should cost soldiery, and have costs comparable to weathered gear (since HA has the additional cost of requiring a clear, whereas weathered gear is essentially "free").
This would let folks who already have all of the weathered gear for their job actually start getting the rest of their BiS in the case that they are severely unlucky with drops.
With the crushing one week lockout on Second Coil, it is EXTREMELY frustrating to clear a Turn week after week and get NOTHING. For example, I've yet to even see a casting drop from Turn 1. Like, not even SEE it drop. And 2 of my 5 BiS for HA come from there. Best part is, both of them are tied to the same chest, so there's zero chance I'll get both in the same week. But hey, I've seen a LOT of tanking and healing gear. Sure is fun to free lot stuff I don't want! In fact, the only thing I've gotten from Coil for my main is High Allagan Belt of Casting. Not even Best in Slot. Woo!
I can't even begin to explain how much less I would hate this game if not for the extremely low chance of getting anything I want (outside of hunts... lol). I think loot should be locked behind skill-based challenges, not just like... Mindless repetition coupled with taking another swing at that slot machine. I'm extremely disinterested in the pattern of 1% drop rates for vanity items (mounts, mirrors, minions), and the overall poor drop rate and extreme lockout timers on current content. I've only seen a primal mount drop once or twice, only seen mirror drop twice, and this is with 100-150 wins on Levi EX, and dozens of wins on every other EX primal (besides Ramuh).
It's very odd to design a game where you can play any job on the same character, then make it almost impossible (unless you are super lucky with drops) to gear more than a single job before the gear becomes obsolete.
