Chocobo Companions and You: A Guide

[Maelwys]

Dont forget, there's many FATE bosses that cast spells with a timed cast, not just simple auto attacks and instant WS spam. Slow makes them cast slower. DR reset after 10 or 15 seconds (closer to 15 is what it feels like), so essentially the boss is slowed 20% for 2/3 of the time, pretty useful. They deal less damage to you, your choco spend less time healing and more time attacking.

Or alternatively; you could ignore the autoattacks, and just deal more damage in the first place to kill it faster (and stance switch if the situation calls for it - healing whilst still dealing DoT damage).

As mentioned at the end of the OP, Chocobo builds rely heavily on personal preference.

You seem to like the Slow: fair enough, I'm not saying you're silly for taking it if you consider it useful!

I consider it useful, but not as useful as a powerful attack or an extra +15% Critical Hit chance, and I place some value on being able to force the Chocobo to spam a Hate generating ability on the offchance that the occasion ever calls for it.

Reducing the rate of autoattacks for a single enemy just isn't particularly important to me. I have never been in a situation in a Fate boss fight where I thought it would be more beneficial to deal slightly less damage in order to have the Boss perform slightly less frequent autoattacks on me, and unlike "player" slows you can't rely on your Chocobo to use it on cooldown.

at 50, in crap gear, my WHM's Aero ticks almost twice as hard as the Choco's DoT, so it really doesnt scale well.

The DoT effect is a bonus to the attack, like a slow or a stun. It is not the attack itself. The individual ticks are weak, but there are a lot of them - the initial 130 potency hit combined with the DoT ticks makes it the highest damage attack a Chocobo can perform.

But I'm glad you're having fun with your Chocobo
