... yes. Because your (or some other Unregistered's) original argument that a 2400 Atk on-element turns into 2600 Atk. So I used 2400 base, which there are none of.Because I actually did the math for Anubis lately. I've made a
damage calc for this, you know.
The result was, swapping in Dark Eidolons resulted in a loss of damage. I got NEARLY back to where I was if I was running double Anubis though, but that's impossible for me. Or did it just barely go above? Eh, it was +-500 in 40k Atk at double Anubis.
However, note that I was comparing really bad Dark Eidolons, as... well, there just aren't any good ones (I wasn't playing during Trivia). To my +99 Tiamats, Miis and Sphinx. As such, the situation for Wind can be different. But, I wouldn't expect much honestly. Reminder that 4% more Elemental atk is NOT 4% more damage done.
