When vauban prime came out he originally needed 14,000 oxium to craft. Playes were furious so DE realized that they needed to lower the crafting requirements and they did, it now requires 7,000. While 7,000 is still a lot for crafting DE decided that it was fair. But why was this considered fair? to quote DE drew "There are nodes like Cerebrus which are a lucrative Oxium spot - consider heading there if you're having trouble finding some." And while this helped with the release of Sotr they changed how the spawning on interception works which means that Cerebrus no longer spawns oxium ospreys. Even with a good farming team to farm all the oxium you need for vauban prime it still took hours assuming you had no oxium to start but whatever this is fair. so now that we cant get oxium their it is extremely hard to get oxium im a good amount. the best i found is on a good run about 150 on ball, europa. compared to the 1000 you could get before this is terrible. To those who haven't crafted him yet good luck and if your like me and need some for the new archwing well like ive been doing with archwing before time to hold off on it again until they fix this. sorry but im not spending hours to farm enough oxium for this. sorry for the rant i just hope something happens cause of this.
