God, I hope Shiva fight is more epic like Levi Extreme instead of something like Ramuh Extreme. To me, Ramuh Extreme was the worst primal fight, not because of difficulty but more frustration and too many instant kill mechanic and how he just stand there and hit incredibly hard with his lightning bolts.

So far the best Primals is Titan Extreme, Levi Extreme, and Gilgamesh. Ramuh Extreme was the worst of them all and most boring, follow by Moogle Extreme.
