For divebombs, due to server latency your character should appear moving out of the ditch before everyone else. If your character is moving with the group on screen it may be too late and you might get hit. Also, if someone gets hit by divebombs they should not try and regroup with everyone else in the ditch as they could get targeted and MPK the rest of the raid with an awkward angled DB. There is enough time for healers to cast one spell during the wait in the ditch so if tanks are dying here it may be a healer problem. BLM can also pop manawall and avoid taking any damage & knockback from DB.

For snakes OT should leave the pit after the 2nd divebomb on the second set, getting into position to pick up both snakes that spawn. Tanks should position the Aesculapius and the hygeia in such a way that caster LB and aoe is able to hit both of them, and to have the MT avoid getting any disseminate stacks. (crappy text diagram below). It does not matter if the OT gets any as they can and should use all their defensive CDs at this point. A common practice I see is for the scholar to drop sacred soil on the OT which signals where the tanks want to gather the adds & for casters to know where to aim LB. DPS should use all their offensive cooldowns here and burn the 4 stack Aesclepius asap.


OT-Hygeia--Aescelepius-MT


Basically you want all snakes stacked on top of each other, and have either tank on opposite directions. When TT comes back down for profusion, make sure everyone but the MT is in the other neurolink as she will immediately plummet down onto the MT. Everyone should also make sure to set focus target onto Twin as she'll start casting Twister. The summoner or scholar should also cast their trait boosted virus onto TT right before profusion to help mitigate outgoing damage.

I hope this makes sense
