It was the experience of the game that brought pleasure and joy, and that's what a lot of us want again. Not the numbers. When I play Classic I want to go through the deadmines with people I like and overcome a challenge together and see myself become stronger as a result. I don't want to play Classic so I can say "booyah! That number is exactly the same as it was 13 years ago!"
The first demon hunters, whether enthralled by the sight of Illidan Stormrage cutting down swaths of demons during the War of the Ancients, stumbling upon a rogue demon hunter in their eternal quest to slaughter the Burning Legion, somehow forcing themselves into the destroyed realm of Outland, or by secret scrolls that have been found in night elven lands, the Night Elf demon hunter has more avenues than Blood Elves to become the predator of demons. Most, if not all Player Character Night Elf demon hunters, are going to be shackled to the fact that they became demon hunters sometime after the War of the Ancients. This is ambiguous due to the information received in World of Warcraft: Legion by the character Illysanna Ravencrest in her Dungeon Journal entry, “The daughter of Lord Ravencrest, imprisoned for millennia in the Vault of the Wardens shortly after the War of Ancients, found herself free after Maiev released the demon hunters from their prison. Returning to her ancestral home, she has sacrificed everything - including her very soul - to defend what she could not during the War of the Ancients,” being taken by some people as evidence of her being a demon hunter either during the War of the Ancients.
Unlike their night elven brothers-in-arms, the blood elven demon hunters have only one true avenue to their becoming what they are: the Sunfury. What this means for the character is that they were part of the coalition of elves to follow Kael’thas Sunstrider away from Quel’thalas in the wake of the Sunwell’s destruction. These same elves were present (and survived) the attacks on Northrend by Illidan Stormrage, Kael’thas, and Lady Vashj as well as the conquering of Outland through shackling Magtheridon. The Sunfury elves who had either proven themselves capable enough, sworn vendetta against the Burning Legion, and remained loyal to the Illidari in the wake of Kael’thas’ betrayal would prove capable of becoming demon hunters in the footsteps of Varedis Felsoul, the first blood elven demon hunter.
2. Your DH needs supplies on a regular basis. They can only carry so much food, clean drink, medical potions and whatever else they want/need at a time. It's pretty realistic that they would need to visit a market every so often, and large faction markets will have the most variety and types of items to choose from. (My DH has been a recluse in the wild for some time, and she is stinky, dirty and has eaten some questionable stuff. This isn't really ideal and a Dalaran doughnut would be pretty flippin nice.)
