we will monitor the environment and feedback from these capes. We won't go down the path of adding a flat single stat amount to capes as that would be too overpowering. We receive a little qq about them atm, but its offset by the fact you have to be lvl 60 to equip it. It's clearly end game, which is our intent.
In the history of items that have been abused and deemed overpowered on OS. It comes from lower level gear with more slots than the general public can get ahold of. Like Worship and Heroic gear in 1-15 or Goddess gear in 20-30 PvP. That's what we want to avoid.
