Unlocking the gear shop is part of the MSQ (You only need to complete the Role quest and have a level 80 job of that role to gain access to that jobs gear). The only reason most people fail to pick up their i430 set is because they complete the quest at 79 and fail to return when they hit 80 and can pick up the gear.
I suspect that the new jobs are getting i430 gear because of how they did entry level cap item distribution this time compared to the rest:
- 2.0 - i50/i55 Job quest relic gear. Wanderer's Palace (level 50 dungeon) has i55 gear as well and is unlocked with a level 47 quest. No gear drops in Castrum Meridianum or Preatorum. DRK, AST and MCH are post 2.55 MSQ so have access to i130 gear from when you get them.
- 3.0 - i148 from Great Gubal Libary (level 59/60 dungeon) or NQ i150 purchased from Azys Lla (HQ was timelocked and required mostly completing the zone before access). No gear drops in Aetherochemical research facility.
- 4.0 - i288 from Castrum Abania (level 69/70 dungeon) with i290 Job quest rewards. Ala Mhigo drop i300 gear including weapons.
- 5.0 - i430 gear distribution unlocked by MSQ. Amaurot (and other level 80 dungeons) only drop i430 Accessories. Mt. Gulg is 68/69 with i418 gear.
New jobs lacking an i430 gear set is going to cause a lot of trouble for new players trying to use the new jobs to complete the MSQ.
