Ifrit in 1.0 wasn't a hard fight at all. Most people tried to rush it by spamming skills/spells, which lead to animation lock deaths and wipes.
In ARR it seems there will be very different gameplay mechanics, and I'm guessing the new boss fights will have more to do with skill rather than following formulas and being patient. Bottom line: Less deaths that are 'purely bad luck'.
Sounds good to me.
