Missing low level class specific armor quest

[Sunglare]

I've started playing a few new characters and notice all the low level class/race specific armor quest are missing from the game. All the NPC's mobs and drops related to the quest. These quest weren't tied to any expansion and considered original content.
One example is the Druid Leafrunner armor set. You get these armor between levels 5-10.
It would awesome if these armor sets were added into P99.
