Unless you post said macros there’s not much we can look at. You can also check out the simulator at ffxivteamcraft, it’s pretty accurate and I’ve been using it since 5.1. Plug in your stats, select a piece of gear and you can import your macro to check out if it’s completing early, not filling the progress bar and thus breaking or something else. As long as you’re not using any rng based skills it might be a rotation issue if it’s not completing.
