The last time I was in Abyssea and parsed my evasion on Dancer, I was at an 80% evade right fighting Pixie NMs in my normal TP gear. There's some shit that I need to use a Hybrid build on, but it hardly matters in Abyssea. Outside Abyssea, the first sacrifice I make is putting on an AGI dagger if I'm fighting more accurate things, and then I can use my hybrid set too (for the VT Dynamis monsters).
At the moment, things like Antares Harness, Calmecac Leggings, Fugacity Mantle, etc. cost me 500 Alexandrite and don't improve my efficiency at all over a 7k NPCable Aurore body and some R/Ex crap.
Edit: To be clear, I've definitely got a max evasion set, I just don't find I ever need to use it and don't want to spend 4mil squeezing out that last 10 evasion at the expensive of DD potential in a set I pretty much never use.
