Like others have said...if you don't care about maxing your DPS then go ahead I guess. I don't macro in any skills at all, except Song + BV + "warning song is up" type macro.
I even have all my songs unmacroed just in case.
That's it. I just...see no point in attack macros. If you're still learning I still don't really suggest them unless you're having a lot of trouble. I pretty much have memorized my rotation so. Yeah. Sometimes I even play without the UI (depends on if I reaaaally need that Bloodletter proc right away).

TLDR just because you theoretically can put all your skills in one button doesn't mean you should.
