Check out this
link here on Zam. There is a Macro for wait but as a previous poster said I'm pretty sure it's for abilities with long cool downs not instant casted abilities only effected by GCD. But for that matter why have one button to do 100 different things (yes that's an exaggeration) because like you said you don't like macros because you think they make the game boring. Making macros that allow you to pair abilities with no GCD like ones that add guaranteed crit are exactly what macros are meant for. Also that link shows you how you could have one macro button to do all sorts of things, based on the Modifier key pressed.
The "one button does my entire rotation" macros don't exist as far as I know and would also probably be against EULA as you would basically be a BOT at that point.
"Wait" works with other commands, but it still goes back to one spell/ability per keystroke, even for abilities (and trinkets) that activate off the GCD. You could, for example, make a macro that will say in /p "Casting squirrel on %t, you hit it, you tank it", then 2 seconds later it will cast Transmogrify on your target. FFXI let you do a lot with macros, but your abilities were generally on a LONGish CD (only a couple abilities were less than 1 min), and you were limited to 6 or 7 lines, counting the /waits.
Also, you could argue that the fall-through mechanic of Rift macros already does a lot of 'playing the game for you', since you can set up a priority list of all your reactionary, positional, and CD abilities into a single macro. Procs that let an ability come off CD earlier than usual to make your rotation 'interesting' even become trivial, as you don't have to watch for the proc, you just spam your one macro.
