I still have a lot of trouble with the macros not firing off abilities when they are ready (like others have mentioned) and or over capping holy power.
Did you make any adjustments to his macro, ms timing, or manually intervene? Or are you just spamming the macros nonstop?
I know ms timing might work different for everyone but what is yours set to?
If it helps at all, I run this macro at 90ms, If I go even slightly over that it will skip abilities and I lose a quarter of my damage. The difference is stark.
You’ve got to find that sweet spot through trial and error.
If I was you I would stop thinking so technically and just go and stand in front of a dummy, hit the key and experiment with your clicks going from super low, confirming everything is hit, then raising up until they are skipping.
Sometimes we get so caught up in things we can’t see the forest through the trees.
