How would you make RDM more complex?

Ugh I know. I'm irked they changed the sound effect for Ruin from what it was in 13, it looked and sounded so pretty in those games. The whole spell is just pretty, just shooting a pearl light with streaks of black in it. So aesthetically pleasing.

I wanted something like XIII's Ruinga so badly, especially if it could later be aspected in a (Summon-)unique way. Bahamut trance --> black hole Ruinga... But alas.
