- Already can buy upgrades from DO Quartermaster. I am seriously considering replacing my alchemist stone with the trinket.
- Mounted battle. Last night I ran the quest where you mount up (no kite) on my Charger and flew around blowing gyrocopters out of the air. As with questing being practice for dungeons, and dungeons being practice for raiding, I can see a new raid boss where you bring your own mount to the fight.
- BOA rep. Yeah, unlike the daunting task of trying to get my disc priest rep for shoulder enchants in Cata (Hated to Exalted), now I can simply buy it. She'll gain rep at 2x the speed he does simply because of a BOA purchase.
Grand Commendations becomes available for purchase at Revered reputation with a faction. The gain will affect that character's grind from Revered to Exalted as well as all future toons on that account (both factions, all realms, all battle.net accounts) for all rep levels, forever. The bonus stacks with both guild and human rep bonuses, doubling the amount of rep received after they are applied.
I just started the quests, so I haven't yet seen all the Queen references..
