I made a simple macro to help with healers/dps in this fight, Ifrit Ex
Code:
/mk ignore1 <me>
/mk ignore2 <f>
usage: (assuming you are a healer, if not then change the <me> with the appropriate healer postion [1,2,3,4, ...]) Right when the first howling wind of the fights targets a healer, manually mark that person with "ignore1" icon (red strikeout 1). When you have the other healer set as focus target, each time you press the macro it will 'swap' the ignore icon between you and the other healer. So simply press the macro each time the Howling Wind wears off, and it will mark the next healer, and take off the previous healer mark. This works well as a visual guide for DPS what to not stand near.
