there is no viable way to monetize 'pve raiding' to make it competively intresting for a mainstream audience to follow, if there had been, you would have seen it done. it's also way to late now in the games life cycle for it to make sense to start trying to establish some type of platform for it.
funny enough, the 'old garde' that got the whole pve scene started in wow realized this even in early vanilla, which is why you didn't see all these former raiders that came over from daoc and eq come running out the gate and raiding absurd amount of hours per week.
pretty much all throughout vanilla (with the exception of late stages aq40 and naxx) you would raid 5 days a week at most, and 4-5 hours per night, it's really the 'kids' who grew up during the vanilla age fault that the pve race has been turned into what it is today. you kept moving the goalposts until volume was at 10, but even then you weren't satisfied and had to push it even farther.
and welcome to raiding today, x number of split raids, multiple mains/alts, tanks required to have every single tank option viable and ready for progress raiding, 12-14 hour shifts, 7 days a week, through holidays, birthdays.
i mean sure, it's great to have hobbies, but before pushing your ''hobby'' to such insane levels, should probably do some research first, and see if it's likely to ever be commercially viable to make a living off of, instead of complaining after the fact that the 'rewards' are so meager.
