The most amusing part of this theory is that it wouldn't even change the way I farm FATEs, so why waste anyone's time. FATE up? Tag in. I'm not going waste time consulting some stupid cheat sheet about what FATEs I shouldn't bother with.
Hang on guys, I need to see if this one can drop Atma.
We've all tagged in, get your butt over here, it's almost over.
On my wa--oh, it's over.
I'm still most interested in this supposed quote (which no one but the OP knows about) that says the Atma drop rate is supposed to be 7~10%. After collecting 36 Atmas, my drop rate is almost spot-on 2%.
