As the topic title says, partially, but here’s complete suggestion:
Separate NPC and player character model limit settings.
The separation of character model limit from player characters and NPC, for PvE it would be an improvement, but doesn’t do good for WvW or sPvP.
If the “Character model quality” option still affects NPCs, then that too should be separated into NPC and player model quality settings.
Since it’s a same old problem with this unified option, we have invisible NPCs, especially during events with large number of player participation.
I’m a casual PvE adventurer, I enjoy combat, adventure and helping, but not farming.
I rarely do PvP or Hard PvE, unless it’s organized.
