In wake of the <wait #> macro command, it is clear that the devs show an interest in alleviating player macro space. However, allowing the /wait command to be placed on the same line as the previous command is, to use an analogy that has particularly amused me, "like applying a bandage to a severed head."
Most unfortunately, with the way this game is designed, the playerbase can only make the most of what they are given by repeatedly switching out different pieces of gear, even mid-combat, to handle different situations. At end-game this can even get as extreme as a need to switch out all 13 slots of non-TP-resetting equipment at once. As much as I would personally like for the need for on-the-spot equipment changes to be removed from the game entirely, that also unfortunately seems extremely unlikely at this point, with more and more situational equipment finding its way in to the game over the years.
The solution I propose? A /equipset command. This hypothetical command is followed by a number. By typing "/equipset ## add", you would be able to "save" the equipment you are currently using to that number, and later, by typing simply "/equipset ##", the equipment that you "saved" is automatically all equipped. Imagine it as 16 different /equip commands, saved to memory, and accessible with one line. Be it front-line, mage, or (especially) both, it is every combat-oriented person's dream to be able to switch all necessary equipment on the fly with just a single command, like this.
Truly, if such a solution to the current macro space problem existed, the devs would have the eternal gratitude of many adventurers within Vana'diel; they already have my gratitude for reading and considering this thread.
