Ok - i did Ifrit Hard mode 3 times and i have to admit i'm amazed of how people fail to dodge the aoe's and the clones.

All 3 times (with different healers) i main tanked and i was perfectly stayed alive without any stress. 3Rd time the PLD tank sword drop, so i think i was from the lucky ones.
Time to farm my 4th Darklight item and move to garuda i guess (:

Once again thank you all for the advice.
