I was stuck at this part on the last stress test as well. Ended up finding a vod on Navashed's twitch that shows the skips. Here you go:
If you can't watch, you basically just climb the mountain until you get to a point where you see that you left the general channel in the chat box. That's your sign that you're "no where". If you /who yourself, you'll see that you don't have a zone by your name. Then you just use the stuck command to kill yourself and you'll be ported to the Westfall GY. I believe you need to delete your hearthstone before doing the warp or else the stuck command will warp you to your hearthstone's location instead of Westfall.
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.
Done, but I actually left Zhovur Axe on there as it will most likely be the weapon you use while DPSing your first WC run. Serena Bloodfeather is level 20 so you probably won't get it until level 18, otherwise you are also most likely still using Staff of Orgrimmar when you ding level 20. Same with Demolition Hammer, which requires killing 24-25 mobs.
An argument could be made to remove Rockslicer but I left it in for completeness.
I think the best solution is to reduce the respec cost to 10-20g. I think that would improve the game. We shouldn't punish players for being flexible and filling multiple roles in PvE, or enjoying both PvE and PvP and switching between specs often. With the high respec costs it seems like the people who are most engaged with the game are punished for it.
In the end though it's not a huge problem if things stay the same. I can see Blizzard wanting to avoid changes like this, even if they are best for the game, simply because they want to avoid the slippery slope of one change leading into many changes and the disaster that could potentially happen as a result.
