Before you get all distracted by the new Lavalon dungeon (yes, the AoE ground damage comes in phases in randomized patterns. There will be moments when you'll have to jump or burrow cos there isn't really anywhere to run...), you'll be happy to know that the Mana Bullet drop rate has been increased.

Mana bullets are also more visible, as glowing blue spheres you can see once they drop. But your time in here will be something of a "dance" (for those of you who may be Naxxramas regulars). Make sure you jump at the right times. Time-consuming attacks like Rolling Stinger (Jester) which immobilize you for a period of time may be a bad idea if you can't move out of the damage range in time.

And - could it be?
Yes, you're not seeing things. A 2nd quickslot bar (1-8 keys) for you people who like to have EVERYTHING at your fingertips. Those who don't need an extra 8 buttons (gasp!) will be able to retract/hide it. Your emotes will now be accessed using Alt (1-8)

These aren't the only changes of course.
But we'll those for later. Ciao!
