It's frankly quite sad that a lot of raiders don't even prize understanding the mechanic. People just memorize a toolbox and not understand why it works.
We desperately need raids to be designed so that it rewards players understanding the mechanics.
To me, the true essence of FF14 raids is not memorizing scripts but to have fights that are like small bite-sized puzzles. E7S's portals and P12S's Classical 2 are mechanics I really enjoyed during prog. However, it's sad that because the mechanics are designed in such a static way, you don't actually need to understand the mechanic to solve it. For P12S's Classical 2, instead of rotating the map 180 degrees in your head, you use a macro version of this picture instead:
And E7S boils down to this:

These complete defeat the purpose of the mechanic. You're not actually solving the puzzle now, you're just relying on mnemonics and brute force memorizing it (or have a second monitor with the diagram on) to solve it.
If these mechanics were sufficiently random that forces you to resolve the mechanic by actually solving the puzzle in your head rather than memorizing what spot you should go to if you get X, that would be a good start.
(Though that will probably cause a lot of players to get upset, since I think the community is now full of raiders who are incapable of solving puzzles in their head and just rely on brute force memorization - P12S really opened my eyes.)
