I think we need a chaos discussion ITT
Keep your mary sue, special snowflake hyper plot armour at home and lets get to work.
The forces of chaos are primal, unimaginably powerful, and older than human minds can understand.
They create entire dimensions to suit their whims. They turn men into monsters and monsters into demi gods. They corrupt every thing and intend to tear reality to shreds.
They are powered by those that would destroy them, they feed on their enemies before, during and after battle. They have endless daemonic followers created from their will alone, they have legions of superhuman killing machines augmented by their power, they have untold numbers of cultists for which the only remedy is exterminatus...
So when you devalue this great enemy, you really devalue your heros. As a victory against such an all consuming enemy should be hard fought, it should be a triumph over heinous odds. It should allways come at great cost.
When a space marine simply tears down a daemon prince or a host of cultists w/o a scratch what is really being said is that the greatest of enemies is an armless retard baby, and we can't beat them because though we have arms our aspergers is strong.
