Application of corruption in 40k

I would like corruption of chaos to have a larger impact on the game instead of corruption only affecting settlements and attrition like in Warhammer 3. Whispers from the Warp and beyond shouldn't be only - 8 public order per turn or +3 leadership to your army.

There should be a system where if you spent multiple turns consecutively battling and taking settlements, you gradually lean towards khorne as rage takes you over where your army gets modifier with a melee attack buff and some sort of trade off which gets bigger and bigger with each turn and it gets harder and harder to shake off as your army gradually falls into chaos. Vice versa with nurgle where you spent too much time recruiting or sitting in a settlement you get blessed by the all loving grandfather himself.

To counteract this, you need to do the opposite of what you were doing for the past few turns or you can attach an inquisitor into your army to negate or weaken chaso influence on your army.

That's my two cents about the development of the game
