How games can have less scripted encounters

[Tunda]

I have been playing games since I know games exist
I would like to share How FFXIV can have less scripted fights:

1- add variants that can be manipulated
2- encounters should have decision making based on the current situation
3- rage mechanic is always scripted but with a twist.. it can manipulate variants like boss attack speed been increase, boss move in unpredicted way.. boss can change his mode between being defensive or offensive based on situation.
4- taking advantage of some jobs skills to trigger more unpredictable boss behavior.

These things are not a new thing.. it is a lack part that I feel from shadowbringers that could come back in a modern more fun more engaging way
