How to earn your free World of Warcraft subscription: Warlords of Draenor patch 6.2

Spend one hour a day to keep the payment for your subscription away.
This guide will show you how to earn enough gold to buy game-tokens and earn your free WoW subscription. It is written for players to maximize their fun-time on World of Warcraft with minimal effort on gold grinding.
It is not written with the intention of becoming the world's most richest player... because we think that you want to play instead of grinding gold all the time.
If you follow this guide the only thing you have to do after 4 weeks in (or 6 till 8 weeks if you want to take your time) is to login on daily bases and grind your garrison. So you don't have to travel, you only have to login with every character you have and grind the resources in your garrison and you are done for the day. If you have maximized your garrison you could easily earn till 1000 gold a day, per character.
Before you can earn enough gold with your garrison you must put some effort the first 4 weeks in leveling characters and doing solo raids. This raids must be done solo, because you don't want to share the gold!
Every week, if you follow this manual carefully, the gold making gets easier because you will get more familiar with the routine in raids and your characters and followers are leveled up more.
