Well it just seems unnecessary to have

Nickname
(Level X)

under nearly every 'live' NPC.

Perhaps behavior like..

If you're on a quest killing blobs, it would show their nickname as a visual cue for players to kill it.

When you enter the room or they become visible to the player, display their nickname then fade it away after a few seconds.

or just a way to toggle it.
