As an Endgame quality of Life available only at Level 30, add an option at the Peddler shop so that we can pay the peddler say 150K Ordo and for 24 hours all of his shop reroll will be for a specific weapon archetype.
Noticing that everyone’s shop spawns are personalized this would allow high levelers to customize their drops.
You can choose categories like: Autoguns only, recon lasguns only, Curio Only, SWords only. etc- using the same categories as the general weapon skins!
Since you can only get Ordo by playing and you have to still check on him hourly, this will increase engagement but also make the engagement feel worthwhile as a QOL.
