New achievements for collecting heirlooms, including Heirloom Hoarder which rewards the Chauffeured Chopper mount which is usable by lvl 1 players. The mount journal text, as seen on Summon Chauffeur, is "Why drive yourself around when you can hire someone to do it for you?" and KoakHoburn is the driver! The 6.1 PTR notes stated that the mount would require all heirlooms collected, but Heirloom Hoarder is just for 35 which is a bit easier.

New achievements for collecting Music Tunes--20 tunes rewards the PortableAudiophone toy. Click here to listen to all of the new music.

Loot from Blackrock Foundry is as follows:
LFR: 650
Normal: 665
Heroic: 680
Mythic: 695

Tier 17 gear with set bonuses is obtainable from Blackrock Foundry. Unlike past tiers, you do not need to turn a token in to a vendor--simply click on the token and it will turn into a piece of armor.
