Most difficult part / worst bottleneck of the Warrior epic quest?

[Soothsayer]

The warrior epic quest is generally understood to be one of the more painful and difficult epic quests to complete in old EQ - certainly not the most difficult, but still a major pain in the ass compared to several other classes. But what specifically makes it so bad? Green dragon scales? The fearsome, almighty goblin wizards in Permafrost? Persuading Kargek Redblade to give you his wax sealed note?

What is the main bottleneck / main reason the Warrior epic is such a bear to complete?
