Please re-evaluate the difficulty of previous endgame content on the DF

In 2.1, if your group failed to dodge a single dive bomb, you were done. Period. There was no recovery. It was a guaranteed wipe. One or two people failing to dodge is recoverable. You are playing that same encounter with much higher item levels, thus buffing your hp. Not to mention there are more than enough people around who have done the fight regularly to keep the wiping at a minimum by now.

My point still stands. The curve on leveling content was way too low and stuff like the Twin dive bombs had no prior proxy to be compared to. Stone Vigil boss doesn't count because of telegraphs, so players were just trained to look down at the ground when things go flying in the air. Enough said.

The ignorance is astounding.
No AoE in Twintania is given any ground marker as indication. This should be your first sign to look elsewhere for enemy attacks.
The very first things in Turn 5 you fight, the Wyvern adds, use Liquid Hell with no AoE ground marker. Next, you get introduced with phase 2, which tells you that you'll be getting markers above your head as indicators as what to do.
When you add both of these two things together, phase 3 (this is the one with the divebomby things!) is simply a combination of the two things you have previously learned.

For whatever reason, with all the information available online, and your supposed 10 years of raid experience you weren't able to put two and two together.
