Game Mechanics: Charmed Pets should drop items given to them

[Zaela]

It's far more likely that the server simply excluded certain NPCs/models from having weapon display packets sent than any client change. What appears or does not appear is 100% up to the server.

Whether an NPC "equips" a weapon, from their loot table or otherwise, is up to the server too. No fundamental reason it has to equip something in its loot table, nor (more to the point in this thread) put something in its loot table just because it has it "equipped."
