The only part of the zodiac saga thus far I had any real issue with was the atma grind. All thore parts were ok - there was known progression and you were able to work towards it - literaly was just a time sink unless you spent time spritibonding for your novus in which case you also had some RNG fun. Atma though was just plain roll a d100 each time you participate in the fate and hope for that 100.
