How do you remember mechanics?

[Sandpark]

Just as important as learning a mechanic is knowing when a certain mechanic is coming.

Watch that targets cast bar, know the enemy skill tendency behind the casted skill.
That informs where you are going to move or what your are going to do.
Set up your position so that you can move where you know you belong in the quickest and simplest manner.

Most mechanics in any fight can be avoided/mitigated if you know the three rules.

See the mechanic
Think know the mechanic
Feel avoid/mitigate the mechanic

When you do it all once in the entire dance, you become an indestructible master of war.
