Exactly, it is currently not logically and also with this reason hard to understand.
I am just one who reads the manual so I'm aware of whats going on.
But the majority is not aware of it, if I see the Advertises for groups on Ghallanda.
The splitting of the already small population is also an issue in DDO you can not merge servers because then the game starts to lag heavily either.
So basically we have to find ways to deal with the situation.
And the early reaper experience penalty is something that split the server population even more than need.
We need more flexibility but the question is where it should come from?
In my opinion, it should come from the characters and their level.
Therefore, a possible way to better the situation would be the possibility to stay longer at a level (no hard cap for quest experience)
Or if one could level back (I call it an Undo function for your character level) if one sees only groups for which one is too high in the level.
Maybe read
this and I plan to do another even more comprehensive Suggestion.
