Stranglethorn is/was the zone I dreaded unless I was a rogue/druid/hunter on PvP servers. I tried my best to stay away but you would eventually run out of quests in Desolace and Shimmering Flats that you had to come there. The mobs in the southern area hit really hard, and the ganking was insane in the northern region. It was a clusterfuck but it was pretty fun when you formed "Protection groups" where you quested together not because the quests were difficult, but to just watch each other's backs for ganks.
Also, you're forgetting about the Troll tusk or beads or whatever quest on the North-west which also had a lot of grinding, but thankfully you had like, 2-3 other quests to go along with it.
