Ideas on how to fix Angron

Here's the thing. I think that pointing him down to being weak is dull and boring and lame, but we know that point him to hell would be lame, so I have an idea of what I think it should be that will fix Angron, and I only ask that you give me your suggestion of you don't like mine.

Here's mine:

Keep the pick 1 of 3 primarch abilities thing, make option 1 a 12 inch charge aura where everything within 12 must charge and if the enemy has Angron as a valid charge target then they must charge Angron. Make option 2 an aura of +2 to advances and charges for everyone including enemies. Make option 3 an aura of Plus one attack in melee for everyone friend or foe like Skarbrand from older editions.

Also just let us rapid ingress him and keep our army rule when he comes back, and his return should have him come back with 2 of the auras active.

I think that the theme of being a Khorne army and just throwing a brick of Fent in the ceiling fan is something that we are missing from current Khornite armies and that should come back in force, because "Khorne cares not from whom the blood flows" used to be a theme of his armies, and I like that flavor.
