A full RNG would not work for reasons people already stated. However, there are certain restrictions SE could put in place to make sure deadly combinations never go together. For example, if wicked wheel happens, it could be put on a separate timer and could *NEVER* happen again for at least x amount of seconds. Then after, that, it is put back in the 'possible random rotation' once more. One way randomness would make the fights more reactive and less scripted would be to have Ifrit use eruptions at whim... not just immediately after he throws searing wind on someone. Plumes could come at random... not just when he lands after Inferno-ing... dashes could start in any area of the map (just like they did in 1.0), but always make him go clockwise so that people can know how to dodge them without an element of surprise. There ARE ways to make the fights more random without making them impossible... but yes, with the current lag, and people needing to *prepare* for everything... fights with more randomness would cause a looooooot of raging, something SE won't want.
