Should you buy an guide?
No... theres alot of free addons and Proffesion guides.
To mining i used this... form 300 - 525 at lvl 80 in less than 5 days
If you ask me.. its not worth to buy any guides... Not even for leveling...
I use 1 simple addons to Level
Lightheaded
Lightheaded is great.. everyone has tryed to search about a
quest on Wowhead... and its annoying because you have to.
1. Minimize WoW.
2. Start an Browser.
3. Go to WoWhead.com
4. Open wow.
5. Copy Quest
6. Minimize WoW.
7. Paste in the quest.
8. Read all the info.
9. And start up WoW Again.
With Lightheaded you need 3 steps..
1. Open quest log
2. View comments.
3. Close Quest log
i would called that... Simplified.
