Can shamans wear mail heirlooms at level 1

A question that gets to the heart of the complexities of World of Warcraft's class and equipment systems!

In World of Warcraft, Shamans are a hybrid class that can wear mail armor, but there are some limitations.

At level 1, Shamans can wear leather armor, which is the default armor type for their starting equipment. However, they can also choose to wear mail armor if they have a mail heirloom piece.

Here's the catch: to wear a mail heirloom at level 1, the Shaman must have a specific set of requirements met:

1. The mail heirloom must be a "level 1" heirloom, which means it was obtained through a level 1 quest or dropped by a level 1 mob.
2. The Shaman must have a minimum of 10 points in the "Mail" armor type, which is a secondary armor type that can be learned through the "Armorsmithing" profession.
3. The Shaman must have a minimum of 10 points in the "Shamanism" skill, which is a primary skill that allows them to wear mail armor.

If these requirements are met, the Shaman can wear the mail heirloom at level 1. However, if they don't meet these requirements, they will not be able to wear the mail heirloom until they meet the necessary requirements.

It's worth noting that mail heirlooms are generally more powerful than leather heirlooms, so it's often worth the effort to meet the requirements to wear them.
