Hm where I could offer advice to you like, "Battleping has solved many issues I've seen for many users." or "LogRep might be able to help you out in this phase", I can't really say that to you on the PS3.
However, I can tell you that if you dodge the very first divebomb, you can dodge the other 5 just fine. There is a very short delay after the first one goes off. She'll pick a target in between these pauses (well before you see the actual circle/beep go off) so you can easily move up early without fear of having the divebomb trigger in an area you do not want. Make a macro like...
Use this right after the 3rd divebomb has gone off:
/p Divebomb macro used! Next in 45 seconds <se.9>
/p Divebomb in 10 seconds <se.11>
/p Divebomb in 5 seconsd <se.11>
It personally helped me. I used an echo command instead of a party wide notice. But what really helped me the most was when the tanks stopped tanking crap on top of us during the 2nd set of divebombs. I feel if you can get your tank to sit up and to the right with the adds, then you all can practice dodging the divebomb for a while till you get the timing down. THEN maybe revert back to the strategy with the tank tanking the adds on you guys as you dodge the bomb.
In fact, if anyone is hit by a divebomb in our group, we tell them to stay outside until the next one goes off (and then they rejoin the group). Even if it kills you, you can still recover at this point by having your mages use a battle raise.
Alternatively, you can actually sit far away from your group (on the other side of the arena or in the middle) so that your group is not hit. What class do you play? Any melee should have enough HP to survive one divebomb with no problem. BLMs can negate divebomb entirely by using manawall. PLDs can negate the pushback by using tempered. ETC! There are a ton of tricks for it.
It really depends on what role you play. The hardest part of this fight is, without a doubt, hammering out the divebomb mechanic and dealing with the adds so that they die before aetheric profusion goes off. Edited, Nov 16th 2013 11:59pm by HitomeOfBismarck
