You definitely start to care when you don’t see a Spike proc because it happens 1ms before you mash the button and see nothing happen and barely hear the sound it makes wondering if you just casted in a sea of particle effects and are now sitting in a GCD.
The visual feedback loop of gameplay matters. Input => output. It should be clear what happens and when.
I actually have a WeakAura play a unique sound effect on successful cast of Mind Spike just so I know something happened when I hit the button since that situation happens often. It helps anticipation of the insta-blast so I don’t repeatedly mash the Spike button because I thought nothing happened.
Play a game like Elden Ring without anticipation animations or on the opposite end of the spectrum play Celeste without any of the audiovisual feedback. Her hair plays a role in the feedback loop. Game Design 101 - the loops have to be clear.
