No the godless are not oppressed or sabatoged. Vorago should not be a member of the Godless and he never should have been associated with them at all. But with that said, yes, the Godless are severely lacking in content. The entirity of Sliske's Game--basically the Sixth Age God Wars--passed without them. Runescape doesn't need a hero...it needs a villain. An all encompassing force of evil that will remain ever-threatening and use chaos to make the peoples of Gielinor tolerate each other, grow strong together, and fight side by side against this evil. I am that villain.
