Upgrading Heirlooms: World of Warcraft

Make heirlooms easier to upgrade, there shouldn’t be 10 different items that upgrade the same heirloom piece. Just have one token for armor and one token for weapons and if you must need 5 upgrades on the heirloom… just make it simpler by having it upgrade 10 levels per 1 token so I don’t need to make sure I buy the correct one to upgrade it.
