== Shared cooldown ==
A shared cooldown is when some spell, item or ability prevents usage of certain others while it is cooling down. It effectively applies the same cooldown to all those that it shares cooldown with.

It is important to know if a spell or item has a shared cooldown, since that is much more limiting than an isolated cooldown. This usually means that you must choose wisely which to use, since you cannot use all within a short time period.
For instance, many potions share cooldown with other potions, and some of the warrior's abilities share cooldown, as well as hunter traps.

Some abilities have multiple shared cooldowns. For instance the shaman's Earth Elemental Totem can only be cast itself once every 20 minutes, can not be cast within 2 minutes of using a Fire Elemental Totem, and triggers a 1 second global cooldown.

Warrior stance changes also fall under the shared cooldown category. Switching stances as a warrior prevents switching to another stance for 1 second but does not prevent the user of other abilities.
