1/ You don't really need to see or work out who has the Mark, like literally. Train your conditional reaction by telling yourself start running as soon the mark appears.
2/ If you have the problem seeing the mark, focus target Twintania. When she takes off to the sky, the focus target bar will disappear. The moment she is ready for Divebomb, the focus target bar will re-appear, at the same time the mark is shown. Start moving.

The key is to have everyone stack tightly altogether,nobody is ahead or behind the party. If everyone, including you, have the same thought process, then nobody should be get hit, save occasionally lag spike or someone screw up. Adjust your pace if you are playing with high ping like me accordingly. Divebomb dodging should be a breeze walk through the park.

@Shioba: 45 sec, I believe it is.
