The Ossiranth Chronicles

In most games, a player's class for combat purposes and their profession for crafting purposes are completely separate and have no bearing on each other.

What if they did?

Most professions are suited to one class or another because of the inherent bonuses they provide or sometimes merely because they provide the ability to craft things that are more useful to them. In WoW, blacksmithing is more useful to Warriors and Paladins because it crafts plate armor they can use (and gives a health bonus useful to tanks when paired with Mining). Tailoring is more useful to Mages, Warlocks, and Priests because it crafts cloth armor, and Enchanting is better suited because of the synergies with Tailoring's cheap disenchantables (as well as being more suited flavorwise, being a magical art).

What if these professions not only gave players the ability to craft and modify items, but also gave bonuses and extra abilities to specific classes? What if players who leveled a tradeskill up enough could gain access to unique classes?

This is just an idea I've been considering. Enchanting is a magical school, and thus would be useful to Mages. Or at the very least being a Mage would allow enchanting to be leveled more easily. At higher levels the Mage could become an Enchanter, allowing them to cast helpful and harmful status spells on friends and enemies.

These wouldn't be straight bonuses in the traditional sense in that they must be taken for min/maxing purposes, but they would be bonuses which change the dynamics of the class that takes them. And Enchanter would be just as powerful as a Mage, they just have a slightly different toolset and a different amount of utility.
