Based off the JWTG pass having extra packs every 250 points after you finish the pass, my thought for the jwa equivalent is a incubator, with 5000 coins, 5% chance to get 5 of the apex the pass is focused on (split 50 50 odds if multiple in all cases) 10% to get 10 unique, 25% to get 25 legendary, 50% to get 75 of the epic, 75% to get 200 of the rare, and 100% to get 250 of the common
50% to get 50 omega if there is one
This incubator will be given every 50 data you get after tier 30
