Turn 5 - We just cannot get through snake phase all alive

[3rdeye]

Dear friends

We been doing turn 5 for 2 weeks now. Conflag was always passed beautifully, but it would stop on divebomb snake phase. Raid Composition is : PLD, WAR, DRG, SMN, BLM, BARD, SCH, WHM

Some notes on our strategy :
1. everybody stack on slope for 1st phase divebomb. Dodge accrodingly
2. Snake spawn, MT take large snake, OT take adds. Melee DPS large snake, BLM and Bard AOE on hygea. SMN put Dots. Hygea would be 60%, and large snake (cant spell the name) would be 85%
3. 2nd phase divebomb-all stack on the slope and dodge. 5th divebomb OT take the other 2 hygea.
4. Rendezvous on middle. BLM LB 2, dps finish rest of hygea and then burn large snake.

Problem is :
> We seem cant get to LB 3, and LB 2 (seem) not enough time to kill all of them
> Do OT and MT need to kite the snakes out of slope on 2nd phase divebomb ? because the stacks and snake animation is covering the green target, and get some of us hit
> how to avoid hygea's debuff on death , it gets melee and tanks. Even if i survived the snake phase, twin's atheryc would kill me cause of the debuff
