How scaling in destiny works
The activity's max level is where you max out at.
Ex: VoG. A 32 will do the same amount of damage and take the same amount of damage as a 30, seeing as the VoG's max difficulty level is 30.
This only applies to raids ATM seeing as other activities have the potential and are known to unlock higher difficulties with DLC.
Ex: In a daily mission, you will take less and do more damage as a 32 over a 30, seeing as currently, we are not at the games highest max level, but they are all coded to be unlockable in the future.
So in Crota's end, scaling will work as follows when HoW drops:
A 33 player will do more damage than a 32, seeing as the max difficulty for that activity is 33. But anything above 33 will act just as a 33. So a 33 in normal crota will do the absolute highest damage of any level seeing as higher levels match its damage.
