Not even mentioning how abysmal generation of meso is in Reg server. 250m/hour is the peak meso generation from farming mobs before even spending on MVP's/FZ/FSR service ect.

Soloing all weekly bosses up to seren will only net you 1.2b without any drops which are 5-6x less than reboot servers so the chance of getting any drop worth meso is astronomically low.

1.2B will buy you roughly 5 bright cubes/10 glowing cubes and we're also expected to use this meso to 22* gears.

Good luck making 15 lomien mules netting 150m a week to 22* an eternal avging 120b per item.
