I never in any way said that swiftcasting an action reduces dps, though it doesn't necessarily enhance dps either (depends on the skill you're using it, for one).

However, using a Swiftcast + Spell macro is slower than using Swiftcast and the spell as separate non-macro buttons, and is also more reliable.

The only classes where I macro two things into one button are Bard, Scholar, and Summoner. For Scholar and Summoner, it's macroing pet commands onto other abilities I use, which is reliable and dosn't slow anything down because pet commands can be given at the same time as other abilities. For bard, I do it purely because with the shared cooldowns, I like to activate Raging Strikes + Quelling Strikes together and Hawk's Eye + Barrage together, but it's unreliable and does slow me down a bit since I have to wait on the second buff to activate, and it doesn't always deign to activate despite there being nothing to disrupt the macro. I could do more dps by activating each of my buffs individually, cycled between GCDs, which is what i do on monk and dragoon, but there's so many buffs for bard, and those pairings share cooldowns, so I find ti worthwhile to suffer a slight dps loss to keep things consistant and have fewer buttons to press.

Black Mage doesn't have that problem, however. There is no reason to combine macros on blm.

If you're not using Manawall and Manaward in particular, separate situations, then you're not using them properly. These defenses are both extremely valuable in the right situations, and you'll want them not on a single macro to make use of them. Combining Eye for an Eye and Pastastasis could be reasonable, though don't they have differing cooldowns? And you don't necessarily want to be using them at the same time either.
