Classes

Nope

There won't be any classes in Pax Dei, a direct quote from the developer puts it best:

What you will find in Pax Dei is NOT a predefined set of things that we have in our infinite designer wisdom decided would make a good tank. What you WILL find are skills,skills, specializations,specializations, armour,armour, weapons, accessories, enchantments, abilities and/or spells that may be useful for someone wanting to be the Tank.
