Soul and Factor Receptors getting added to the Unique Weapon Badge Shop does help immensely, however it doesn't fully solve the problem, since PSO2es in Japan can give them in higher slots, and sometimes as just a random gather reward which only takes like 5 seconds, once per day, but it's RNG, though slightly common, and it also gives some gathering materials. I assume Factor Receptor on a weapon is also supposed to be a thing, and the Soul Receptor weapons we have are only in the Challenge Mile Exchange as a 5 Slot for 5000 CM. I'd like to suggest they add 6 and 8 Slot weapons and units with Soul and Factor Receptors, and/or decrease the price on all of them, or have them have a chance to drop while doing actual gathering to simulate the gathering in PSO2es. We're also still missing Gift Receptors, and Extreceptors.
Side Note: PSO2es also gives 1SG, 10,000 Meseta, 100,00 Exp Ticket, 300 FUN, 40-80 Excubes, and boosts a Collection File once per day, and Idola: Phantasy Star Saga can give 100SG per week (they did give it to us once), so I think they should send those as continuous login rewards via the Visiphone. Then add all the rest of the cosmetics from these games (we did get some) as a permanent exchange shop, with the badges always being available and free. Possibly even allow Mag feeding and Buying and Selling on the Personal Shops via a page on the website, to replace those features from PSO2es.
