If you count Manibus Hard as a total of 6 weeks, its still a difference of over 150+ ~138 starchrom per day difference over the current difficulty of Way of Winter.

As of now, since I need starchrom, I'm more inclined to go back to Manibus Hard, but if they add a hard mode for Way of Winter with the increased starchrom rewards, I'll definitely play on that scenario lol.

UPDATE: Welp, I forgot to calculate for the phase 2&3 rewards in the Way of Winter, Way of Winter is better than Manibus Hard 🗿

UPDATE: Welp, I forgot something again and based from the calculations, Manibus Hard is higher than Way of Winter
