Evis has been better than DE for a *long time* it's just been much more dramatically noticeable now.
Highest unstacked Evis I have done was 4.6k to Iron Giant in Abyssea-Altepa, no bard/corsair/drinks at the time.
At the time I was using VV/RR/AO. Right now I personally think the best Atma combination is going to be RR/Apoc/AO. Haste Atma suck because full AF3+2 and Bullwhip alone get you to 23%, it's always going to be major overkill.
