Hey, I am taking a break and gonna share a gil making method from me.
As Bluemage with Basic Instinct you can clear T1 Synced kinda easily. The boss is too slow to catch up to you under normal circumstances. But will still hit hard, especially with enrage buffs. It might 1 shot, if you mess up.
I would say the drop rate for the ADS Plating is around 5-10% based on my drops. Maybe I got even a bit luckier than that. It feels a lot better than ADS Illuminant from T5 at least.
The ADS Plate is selling for around 6-7 million gil in Europe and NA. Japan a bit less.

You will need to use healer mimicry.
I have optimized the skill loadout further. Candy Cane#120 does only 250 potency and 50% less to the remaining enemy. Initially this was nice as I required skills with faster cast time to kite more. But now I would take Eruption#45 for the flat 300 in the burst window.
Using Supramax-Potion of Intelligence in HQ will let me finish the fight almost immediately in 1 Moonflute Phase, when the boss splits at 69,9%.
I am not sure if it is possible to get 2 ADS plates from 1 encounter, but my strategy is focused to allow that. If you stop running, the boss has a high tendency to enrage and fusion together again, even at a distance. So keep running smooth smaller circles if possible, not using all of the arena.
As a failsave when the boss does fuse: The boss will also almost always use the red path when kiting. You can use the green one if you fail to kill it in the moonflute burst phase, enables you to fit a cast in even if the boss has high enrage stacks. And then continue kiting. This is why your kiting should be clockwise.
Optimal clear times are around 4min. I guess at least 1 drop per hour is very well possible.
I know some people will need those items for their crafting logs and housing items, so this will be an alternative. Good Luck.
