So, I had boosted a White Mage and I found that casting Holy 1 is like a flash bang in my face.

I am still sort of new to the community but what I ended up doing was creating a macro that turned off self player effects, cast holy then turned self player effects back on. There is a 1 second screen shake after the cast goes through.

Anyways, it helped me a bit. If anyone wants to try it out, here it is.

/battleeffect self simple
/ac "Holy"
<wait.3>
/battleeffect self on
