Interesting heirloom changes:
I'd like to take this opportunity to provide some information about heirlooms:
- We plan to them available again with patch 6.1. They are currently being redesigned to fit the new stat system.
- The heirlooms will be sold for gold and base level will go up to level 60. Once you buy a heirloom, it will be available for all characters on your account, as toys and pet are now.
- The base heirlooms can be upgraded to Tier 2 (usable up to level 90) and Tier 3 (usable up to level 100) in exchange for emblems that will be obtained as a reward for some tasks completed within the game.
It's a rough translation from the EU forum on MMO-C.
