I hear so many people being really happy with the macro system... maybe it's just the classes I've chosen to play but I don't find that I use them for much.

War ... I have 1 macro and that's to tell my party that my stun is on cooldown (and it's not on my stun in case I mash that button)
Bard ... I have 1 macro to tell my party that my silence is on cooldown (again not on my silence because I might mash that)

Conj / Arc ... I have macros on bar 10 next to the party menu... so that it casts cure/physick on the person who's name it's next to.
... I have a macro for Fluid Aura that marks the target as <bind1>


Sure they're nice but I just never find myself in a skill order often enough (where I don't want to switch out for something else) that I want to macro multiple skills together, and I prefer to use my offensive skills to burst / defensive to protect against burst. My DPS might be higher if I rode them all on cooldown but I don't NOT have them when I need them.

For Crafting I have 2 macros... 1 for 40dura items and 1 for 70dura items.
