I like it better without ammo synths - between glimmer, shards, strange coins, synths, radiant materials, ascendant materials, hadronic essence, plasteel plating, saphire wire, weapons parts, crux's, orbs, cores, etheric light, etc., the system put in place during D1 for consumption, upgrade, conversion, barter and purchase needed to be simplified and streamlined in my opinion. In fact, it should be simplified even more. Ammo synths are not the problem, lack of ammo in the raid is. Therefore, instead of bringing back synths, just increase the drop rate.
