In PSO2NA lots of weapons were removed from drop tables, probably to prevent overwhelming new players and to remove any weapons that used the old grinding model (similar to units now but with much more unforgiving success rates).
A lot of these weapons have appealing aesthetics and even unique visuals when used, and many of them are straight-up nostalgia weapons from previous Phantasy Star games. It's a shame these aren't available to use as weapon skins! This will become even more glaring when the weapon form pass system gets released in full by Episode 5.
Please consider giving us a method to obtain these weapons, either as camos or the weapons themselves to later use for skinning over our current weapons!
I'd list them all but that would require some form of collapsible spoiler-box to keep the post tidy. Just know that if you remember a weapon from PSO or PSU, it's probably existed in PSO2 at some point and was made unavailable here.
