Rotation Condition Help

[Arkatetk 0]

So I am creating my own Protection Warrior FightClass file. What I am trying to achieve is the following;

• Cast Ignore Pain if neither Focused Rage or Ignore Pain Vengeance buffs are present.
• Cast Ignore Pain ONLY if Vengeance: Ignore Pain is present.

So what I've done is created two Ignore Pain spells in priority. One that casts only if neither are present and one that casts only if one is present. The reason I do this is to start the rotation you always want to begin with Ignore Pain and not Focused Rage. However, the buffs themselves only appear once one of them is applied. Is there a simpler way to make it so that Ignore Pain can check if neither buff is present and then only recast Ignore Pain once of the buff is present? Thanks.
