Yes, but what event Eidolons have 2400 Attack?
Let's see, it's:
None.
... well, shit. But if we're talking with +99s:
Sphinx (Light, 2118)
Tiamat (Water, 2262)
Fleurety (Wind, 2130, coming up in March)
Honerable mentions to Mii (Thunder) and Ikaros (Wind) who are just barely under 2400 at +99. Also, this list is only up until August.
See the little problem here? Chances are high that your Wind Eidolons will be closer to 1500-1800 base Atk, which can be increased to about 1800-2100.
