How will the AF gear be obtained ?

If we look at FFXI SE has done this 3 different ways. I hope they don't go the AF2 way with years of farming dynamis to get a set with horrible drop rates. It would be fine if they went the abyssea or AF1 route.

AF1 obtained by quests/coffer key hunts, which mostly were talk to npcs, find a ??? / trade item to a ??? / kill NM / kill countless mobs for coffer keys open the chest and get your AF

AF2 Random drop from dynamis.

AF3 Found in abyssea, kill some easy popable NM several times till you have enough seals / upgrade items for the piece you wanted. Each NM could drop 4 seal types. Tedious but easy to do and you could get the piece of gear you wanted fairly quickly. This was one of the better systems.
