My suggestion for classes in TMW is a follows:

Added to the menu buttons on the top right of the gameplay screen there would be a class button. We could also call classes job, proffessions, etc. Choosing a class will give you stat bonuses, but will restric the spells, weapons, and armor you can use.

Some potential classes:

Warrior:Basic melee fighter. User of swords, axes, maces, hammers etc. Not that great with ranged weapons Ninja:Can use most swords and knives, along with thrown weapons(throwing stars, kunii, sinban, etc.) Rouge:Can use most knives and thrown weapons. Some offensive magic. Mage:Your basic magic user. Primarily elemental offensive magic, with some healing magic and summoning magic. Druid:Nature mage. Can use some bows, but primarily relies on summoning magic and nature related spells (entangling vines, wild shape)

If you have more ideas, post them below and please don't put them up with my ideas:
