/click is also useful for timing spells with a cooldowns and triggering proc-based spells. I can also see the point of doing this with Macroon. What if it breaks or is no longer developed? You have to rewrite everything. I think it's wise to plan macros and your setup to function apart from addons. I was very dependant on a Warlock addon and I was useless for about a week after it was broken by 2.0.
