CLASS ARMOR AND WEAPON STYLES
Here is where CLASS RANK REWARDS are important.
For example there are 9 pieces of armor, head, chest, legs, hands, feet, wrists, waist, back and shoulders, 3-4 armor types plate, mail, leather and clothes.
There are going to be at least 6-7 different weapons, and the Witch will be able to use at least 2-3 of them (I still don't know how weapon system will work).
You can make maybe 2-3 different Witch(class) armor styles, for example:
Noob Witch armor and Ancient Witch armor.
AND/OR
Cloth Witch style, Leather Witch style, Mail Witch style and Plate Witch style.
Almost the same style but Ancient style more detailed than Noob Witch.
There you have 9 pieces of armor.
Plus 9 armor styles recipes that CAN'T be sold nor traded (class exclusiveness) (for crafting and transmog)
Plus at least 3 weapons.
Plus at least 3 weapon styles recipes (for crafting and transmog)
That's 24 rewards for each Witch style, we have at least 2 Witch Styles, that's a total of at least 48 Class Rewards for at least 48 Class Ranks.
Also the styles can be used for any character in your account, the only way to get them is leveling up one character from that class.
