How games can have less scripted encounters

[Raikai]

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

Adding variants could go a LONG way, especially things like 'dpsbusters' or something that the healers need to pay attention to. Heck, the fact that healers can literally spreadsheet their whole healing plan says volumes about how stiff their design is. And what's even interesting about following a spreadsheet instead of improvising and thinking on the go?

I'm of the opinion that healer dpsing kits should remain with the level of complexity they have today (although I strongly disagree with a filler nuke+dot copy paste for everyone), but they need to look more to the act of healing, and by that I don't mean "give more hard hits to heal", but instead they should allow players to express their healing skills by putting their brains to work.
