What's with all these people single-targetting during big pulls in dungeons?

Imagine a scenario with 4 enemies each requiring 2000 potency to defeat (for a total of 8000 potency). Your regular 1-2-3 combo does a total of 150-280-370 potency (total 800 potency every 3 Gcds) which results in you needing to perform a total of 30 Gcds to kill all 4 enemies (total 8000 potency).

In contrast, your AoE action has the potency of 130 which when hitting 4 enemies gives you a total of 520 potency per Gcd (in which we compare to the 1-2-3 resulting in 1560 potency every 3 Gcds). In this case, you will need to hit at most 18 Gcds to defeat all 4 enemies (total 9360 potency).

*snip for brevity*

Oh! I see it now! The party ends up taking less damage in the encounter using AoEs rather than burning down one mob at a time. Thanks for explaining it in such a clear manner.

Of course, there will always be exceptions. Some mobs are just too dangerous to not burn as fast as possible. For example, mobs which take control away from your character.

Anyroads, I appreciate the time you took to answer my question. I'll improve my play.

*writes down* In general, AoE at three mobs or more.
