You don't need macros on war. The only "macros" I ever used since starting the game I took off.

1. Berserk - "pwease clear my pacification" - By the time they do, it's just about over with anyhow.
2. Brutal Swing "I jes stunned!" - 9/10 times Brutal Swing is being used to add to DPS rather than Stun. There's not much content to stun anymore.
3. Doubleling up on abilities - Like Convalescence/Mantra... Bloodbath/Berserk. Again.. just not worth it.
4. Provoke + Tomahawk - used it alot in the beginning, but it's more beneficial to seperate the two so I can do things like finish a Butcher's block combo directly after a Provoke.

There is no need for Macros on War, unless you just happen to be doing something that communication helps for.

For ex.. Ramuh I use "pick up orbs " "don't touch orbs" macros to help people know when to collect an when not to.

Outside of that, every content I do that communication is a must I just use teamspeak for anyhow.
