Tiragarde Sound and Stormsong Valley are both fairly similar zones, but Stormsong is a little longer, meaning that you might not even have to finish it to hit 120. Tiragarde also comes with a bit of a warning. There are plenty of side quests to do in the zone after you finish the story quests. Don’t do them. It’s not worth the time or the experience you’ll get.
I'm working on getting this one too but from what I can see, while it's nice having an actually completely free combat bonus that also looks pretty sweet as an Engi, it's still only useful outside of instances and a minor bonus at best. The craftable constructs aren't sellable so there's no way to recoup the costs of crafting this too. Another one I'd recommend against, unless you like having the mech guardians.
As a new Orc on the block, I have trouble leveling efficiently. Recently, I read a review about Zygor Automated Leveling Guides. The add said these guides were useful to new players who frequently lose themselves in the questing game and fail to level effectively. The problem is the price. As a graduate student, my time and money come at a premium, and I really don't want to sink $60.00 into a leveling helper if it not all its cracked up to be. Has anyone used such a method successfully? I don't want to waste my time or that of others, but I figured posting this question was worth a shot and it would certainly be much easier on my bank account, especially if Zygor Guides is just trying to pull the proverbial wool over the eyes of new WoW gamers. Thanks for your comments in advance and Happy Holidays.
-Bugs- There aren't too many glaring bugs anymore, but you will certainly encounter some. The pathetic thing is that many of the bugs you'll encounter were reported repeatedly during Alpha/Beta and still weren't fixed. Some bugs were discovered after release and players were able to abuse game mechanics without repercussion unless they were one of the more serious offenders. This gave some players a significant advantage over others because they used exploits and at the start of an expansion, that is the time when it's most impactful.
Be cold-blooded about admitting that you've taken a bath on an item. If you bought that sword for 5g, listed it for 10g, and the listing cost is 2g50s each time, after two times it had better sell just to break even. Once you hit that point, don't keep listing it over and over in desperation trying to make something off the AH. D/E it, or vendor it, and move on. Lesson learned. Don't get trapped in the fallacy of sunk costs.
 Void elf (7.3.5) - "Many have sought to harness the corruptive magic of the Void. Most who tried have fallen into madness. Determined to use this power for the good of Azeroth, Alleria Windrunner is the first mortal to succeed at defying the shadow's whispers. Coming to the aid of a group of her kin who nearly gave in to the darkness, Alleria has vowed to train these Void Elves to control the shadows within them and pledge their newfound powers to the Alliance."
In addition to questing and running dungeons in the Broken Isles, players should also remember to visit their class hall, which is like the garrisons from Draenor, but themed around your character’s class.The quest lines in your hall provide valuable experience and open up important features, like artifact weapon upgrades, that will drastically up your character’s power.
