Getting to level 8 the normal way isn’t that much longer and far more enjoyable 
Trying to maximize reputation gain from low level quests is what will likely be the death of me. I’m wrapping up the quests in bloodhoof village, and I want to get the quest done in the starting zone in durotar and tirisfall glades. but running around with absolutely zero bonus stamina at level 9 means I’m quite intimidated of the hike across the barrens.
It’s honestly fairly easy.
There’s one tricky spot after the gold road bridge where hyenas path close to the road but if you just wait for them to path away you’ll be fine.
I would imagine this is quite a bit safer than running through the wetlands at lower levels.
Don’t.
I am compelled to do so because Hunter is my favorite class at level 60, and Druid is my favorite class at level 70/80.
Drop the homophobic BS.
