How games can have less scripted encounters

[NekoNova]

We have to get these things to implement randomeness to fights:

1- 2 min window should be scripted
2- shuffle mechanic based on specific criteria
3- moment when boss move to high dps member and focus on them doing avoidable mechanic and tank have the ability to do mini game to knockout boss

That will make tank like a real savior of the team not just a hitting bag

1. Why? You're trying to get rid of it, remember?
2. Just a matter of time till players figure out these "Criteria" and tweak the fight by setting up those "Criteria", this is called seed-manipulation in most speedruns because they know the exact sequence that's going to happen
3. You mean like the Susano fight? What's the point, this is just another scripted phase then.
