When I get my daily hunting log, I check the FATE enemies first. When I know the FATE and know it spawns in a normal manner, I try to do it. When I do not really know the FATE or know it is a rare spawning one, I just trash the book. Animus told me one thing: to never ever wait again for a FATE. Waiting 2 hours and zerging it down in under a minute? Never again going to happen for me. I rather make extra and unneeded tax declarations.
