I wanted trash loot on InstanceLoot so I decided to hack it in as first contact to lua code. Only the expansion raids have loot and it can be viewed on the lower left corner of the instance map. Not sure if there's anyone else interested but in any case here it is.
Touched Files (search for "Trash Loot" to see them):
- Title not setting on bosses (possible Cartographer bug)
- "Trash Mobs" string isn't localized
- Drop Rates aren't "accurate" (don't think it matters much though)
