The next World of Warcraft expansion, Warlords of Draenor will soon be upon us. The level cap is being raised from level 90 to level 100 so there isn't too much you can do now to get ready for it. If you are below level 90 and would like to get there quickly you can check out our WoW Power Leveling Guide (that will be updated soon for WoD). But remember that all players get a free level 90 character when they purchase WoD.
Everything you own will be replaced pretty quickly when you start the new expansion so there's not really anything you can do about that now. You can however prepare yourself in one way, Gold! Getting tons of gold in WoW is rather easy and having a lot of it will prove very useful in Warlords of Draenor. By the looks of it, you will have a lot of thing that will drain your purse in WoD. Garrisons being the main thing. But in addition to this, having gold to by gear from the AH can be advantageous in the beginning of the expansion, especially for casual players.
