A zygor guide is absolutely not a reliable investment, it's not going to be resaleable so you're never going to make your money back. As a purchase, at this point in the game if you need a leveling guide you shouldn't be playing the game. Leveling up is so fast, quests are easy to understand and chained, and the game puts a mark on your map for where to go for around 90% of quests. If you can't manage to follow in-game quests (possibly with a free add-on), what do you plan to do when you're done leveling? Raiding and PVPing don't just happen for you automatically.
There are times when you will be fighting things a couple of levels higher than your character. This is easy enough for some, but others might find that they need to be a bit more careful. If you let yourself get a couple of levels ahead of the guide then this ceases to be an issue. If you look through the configuration options you’ll see a place to set your difficulty rating.
Many of us accept Zygor Guides fulfill our responsibilities. So we pursue that Zygor Guides regardless of whether we do not that adheres to that. That may be you’re not doing Zygor Guides but you are troubled with it and hold tight it suppressing your passion. Don’t you wish to come out of it? Yes, you’re always thinking about Zygor Guides but you will not are aware of the how than it. But they know it with a course absolutely help appear and does one actually wish. This all may be to be an impossible proposition.
Disclaimer: Part 1: If you buy the guide through the links on this page I do get a cut. Part 2: With the guide I have leveled one Rogue from 70 to 90, another from 1-90 (yeah, two 90 Rogues,) a DK from 55-90, a mage from 1-90, and various others. Family members have leveled an assortment of other characters, some with little gear, others with full heirlooms and Recruit a Friend (3x XP.) So I confess, I like this guide. We all do.
