Why encounters with a difficulty slope are bad

[Almalexia]

my main issues is repeating the first phases again and again and again and again until u learn the last 1 enough to win...by the time u learned last 1 , the first phases are done blindfolded....

Shiva EX is the perfect fight in my opinion

This is a model EX encounter. It's not too easy, it's not too difficult, and the AI has some variance to keep things interesting. It's not full-on, sear-you-in-the-ass 1.0 Ifrit EX random, but maybe we will get there one day.
