THIS IS HOW I CLEARED DARK DECIMATION WITH 4 STAR GEAR 12 CHARACTERS

I would add that it's good to avoid using your Maul's Fracture on the enemy Maul. 

Try to get your CD on maul back so you can attack the enemy Maul with specials, kill him, and then you'll have a much easier time tackling Savage while he's Fractured. 

But other than that small addition, you've done a great job writing this up. Thanks from me and on behalf of the many other people who will get use out of it.
