Why you should have at least one macro with a /p line.

[Clavaat]

Our group doesn't use VOIP. Macros with /p and <se> are very helpful.

I spam the one for Blighted Bloom in T6, Twisters, and even have a divebomb macro that counts down when the 2nd set will occur for T5. Back in the early days I used one to call out Plumes on Titan. Even pickups appreciated having another indication if they got lost in the rotation at some point. Helps a bunch.

It's also nice for Silence rotations on my BRD/MNK.

EDIT: That being said, I don't use these in regular dungeons. I swap to the regular ability.
