Focusing on the Round and Sophic birds when unsynced:
Thordan EX:
I've seen people who suffer the same fate as a certain NPC, thus wiping the party. Some even botch the eye mechanics and run around to the outer rim like headless chickens.
Sophia EX:
People hit the PLD add recklessly and get flung off the platform. In addition, some don't even do tilts properly and fall off to their 0 HP doom.
I've had better luck clearing both Thordan EX and Sophia EX when they were synced back in Heavensward.
In short, even when unsynced, please do mechanics in EX trials to clear them more smoothly. Otherwise, you're better off doing Praetorium 3 times for each of the birds if you want them so badly. (This is especially for those who flub the mechanics over and over again after clear explanations are given.)
