As am I.
It is the save the game patch.
It offers two new landmasses. Two new dungeons (Mechagon split into two). A new raid. A new world quest system. A new Azerite armour system (and the jettisoning of the horrendously flawed old one) and laying the ground for the next Allied races (Vulpera, Mecha-Gnomes and Ankora are all candidates, with the first two being practically shoe-ins).
Haven't felt this excited about WoW news since the 8.1 preview but 8.2 is going to be a gargantuan patch, maybe even the biggest they have ever done.
