"Add new features to WoW"
One of the reasons that has contributed the most to make World of Warcraft one of the most played titles in history is, without a doubt, the infinite options offered by its interface.
So large is the interface that, in addition to the game settings, as well as graphic options, sound and keyboard and mouse settings that allows you to use other tools that modify the game itself, adding new skill bars and other content thanks to so-called "addons.
There is an indigestible amount of addons circulating around the web, but, without a doubt, one of the most outstanding is Carbonite.
This one, supposes a before and an after at the time of carrying out the missions. Finding a hidden NPC or finding the walk zone of the target monsters won't be a problem again. Carbonite is in charge of pointing out on the map (even in coordinates) the position of what we are looking for.
Some see it as one more addon, others as one of the key elements when playing World of Warcraft.
