Yeah, I'm hooked too. They made the game so much better with the expansion. Unfortunately the game is still fundamentally broken in certain areas and you can see that they tried to make the best of it. Pretty much everyone right now only has stats in their primary + vit because of Loot 2.0. Usually in the 4-7k range. The other stats are 77. This is a sign of a broken mechanic. The other thing is how weapon DPS + critical hit is the only thing that matters. As such, any weapon with out a socket + emerald is worthless.
That said, the game is still really fun. Got my HC Wizard decked out with +50% CHC and +34% damage to Disintegrate. Melting faces.
This update is crazy. I can attest that the drop rate of legendaries in rifts is definitely higher now. I've gotten 2 of them in a single rift several times since the update.
