For all the people, including myself, that do not want to spend hours doing the horde quest in Jade forest called Forensic Science, it is not a bottleneck in the true sense of the word.
Download Questie for 5.5 and you can see that going to Dawn’s Blossom is the best way. Clear every quest on the map that you can, do both of the starting dungeons and their in-duneon quests, and you will reach lvl 86.
This unlocks the quest at Dawn’s Blossom from NPC Bolo, called His name Was… Stormstout.
Now you can just go to the next zone and procceed with usual leveling, come back to Jade forest after a week when the madness is over.
, and how anti social the game feels without it.
