Why do I suck so much at RDM?

[IchiExorz]

Red Mage might be simple to play but it requires you to pay attention to other things compared to other jobs.
It's not a set rotation to remember but its more "reaction" (or prediction) based and that way of thinking is something you will get used to over time.

Always have your gauge in the back of ur mind or look often at it because what element you will have to cast next depends greatly on it.
You pretty much have 4-5 seconds to think about it after you cast jolt/impact whether you should use your Veraero or Verthunder in your next Jolt/Impact rotation.
Jolt/Impact/Scatter always give equal amount of White & Black mana so you will already know before you start casting Jolt which mana will be lower so you know which skill you should use next.

Impact has a lower priority compared to your other 2 procs Verstone & Verfire so always cast Verstone or Verfire first when procced. And if both are procced always use the one of the lowest mana.
Only use the Impact proc when you generally should cast Jolt. Impact is pretty much a stronger version of Jolt. Generally you should be casting Impact whenever you should be casting Jolt & you have the Impact proc up. The less you have to use Jolt the better.

The general idea of Red Mage & reaction timers is think about what you should cast as soon as you finish your dual cast. Think before you have to decide so you won't have to "react" to what you should be doing.

RDM might have an easy rotation but it has a diffirent type of difficulty that might take some time to get used to for some people.
