I dont like this detailed information being always shown without being dependent on my characters at all. Its a meta feature put there to make things easier for general mass audience convenience.
Since it was the same in DoS games and they didnt want to remove it there i doubt its going to happen and there is always enough players complaining against removing it, crying about it.
But - it could be disabled on some sort of "hard core" difficulty level, it could be an option in game options.
Even better if it was tied to character skills like Arcane knowledge and Nature lore. Discovering actual lore info in the game itself, either through discovering books and through dialogue, or by fighting a specific creature which if successful would reveal such specific info about that class of creatures. Right now our Nature skill does already serve a similar purpose in some few rare moments, such as Kuo Toa encounter, but to make it fully implemented in that way would require some deeper work by the devs.
And im pretty sure they wont do that.
As an alternative, simply removing that meta info for a specific difficulty level would be relatively easy to implement. And special early encounters should definitely not be scaled down at all.
