Hey guys, here u have all in one place:
1st as Aristodamos said best farm is around /way 72, 36.
Kill only Ritual Scout they have 98% drop rate, drops 3-7 [item=202017] and [item=202018] around 14% drop rate
They kind spawn slowly but pay attention on lava circle on ground they spawn(jump out) from it, I didn't know that when I started farm
2nd each 5 [item=202017] or 1 [item=202018] give you 1 language skill, when you reach 100 you learn new permanent language [spell=403661] (Furbolg language).
IT IS NOT giving you reputation, but its unlocking side quests
3rd if you are not tank gear up first so it will be much easier to deal with farm.
As shadow priest ilvl 492 took me less then 1h to farm and do all quest's.
Just stay and farm until u get enough [item=202017] combine with [item=202018].
Example 450 [item=202017] and 10 [item=202018].
You don't need to over farm because once you learn Furbolg language you don't need [item=202017] and [item=202018], sell them, don't throw them like me :o)
Hand them to [npc=189401] /way #2024 66.93, 12.77 Sonova Snowden
I used keybind "interact with target" (you can search in options) and macro for [item=202017]
/run C_GossipInfo.SelectAvailableQuest(72586)
/run AcceptQuest(72586)
/run CompleteQuest(1)
/run GetQuestReward(1)
Hope I cover all, wish you a good farm :o)
