Something that would help builds in this game is if the quest rewards were more dynamic.
Right now, you select 4 pieces: Plate, Chain, Leather & Cloth
Each of the 4 pieces is statted for Knight, Warrior, Rogue and Mage generally
My suggestion is to make quest rewards a 2-part process:
1. You choose the reward type: Plate, Chain, Leather or Cloth
2. You choose from 5 stat archetypes: Tank, Strength DPS, Dex DPS, Int DD or Healer
The reward piece is completed and given to the toon.
