Ok I’m gonna give the benefit of the doubt and assume this isn’t a troll post since based on the fact you don’t even understand how DoTs work, you’re probably just new.

I’d suggest you look up some PLD guides. Since they can go more in depth than any answers you’ll get here.

But in general, rage of halone should only be used to gain an enmity lead, never spammed. Once you have the lead you can usually hold it with just your dps combo and you’ll be doing more damage as a bonus. While you’re new you’ll probably want to be staying in shield oath but even then you’ll want to use your dps combo once you have an enmity lead since the shield oath enmity bonus will be more than enough to help you hold the lead.
