My group decided to forego the entire starting zone. I will main as a Warlock but due to the imp quest, I'll just roll my warrior alt so we can split asap. We plan to grab the "Go to razerhill" quest, grind all the way there, and then grind back to Sen'Jin village so we can hopefully start grabbing the quests. We learned that when we skipped Sen'Jin, we out leveled everyone very quickly, but then about level 6 the quest turn in allowed everyone to catch up and pass us up by level 8. Seems the quests are worth more XP.
Ya @yoyomyhorde , the vast vast majority of the guide is there. I'd say about 95%. There are a few gaps where other guides might tell you to grind that I'm actively looking for ways to improve at the moment without telling players to just grind or do a dungeon but I'm running out of content in the game so will have to resolve soon. There has been a lot of work put into a route that will work on classic including the entire zones of Swamp of Sorrows and Silithus, new quest lines that are efficient along the path, reordering of zones, and giving optional dungeons. Varrak's speed run was very helpful with efficient questing routes but as you mention the exp rates on that server were incorrect. If you notice any particular issues you'd like me to focus on feel free to send a suggestion to me on the site. Always looking to improve.
