Macros can assist in having fluid rotation. As someone pointed out, they clean up the bars, too. I currently work with 10 hotkeys in my standard boss encounter. 5 of these keys are macros. One marks and casts tomahawk. Another puts most of my buffs into a one button spam mode. And so on.

I can literally open up on a boss with 2 buttons, then just hit whichever macro button applies in my sequence making use of the /wait 2.5 second command to automate that particular rotation. If I didn't have abilities grouped as such, it would be more buttons to press, more opportunity to screw up my attack orders, and I would probably miss fluid rotation, which would contribute to less damage, which would make me a less effective tank.
