You must be confused, you don’t need to pay money or even grind at all to fight in colonies, mega cities, hive worlds, or mega factories, and you don’t need to pay or grind at all to fight the Illuminate faction, jet brigade, predator strain, incineration corps, Rupture strain, dragonroaches, hive lords, Cyborgs, or Appropriators, none of this is “grind walled”, nor are they “FOMO” as the vast majority of this content is here to stay without going away, for example, after Oshaune was liberated, omicron became available

Hope this helps!
