i booted up the game again because a passed by a video of trump saying they were giving away a free deck with decent cards in it and its like "okay free stuff".
so i played a few games with it (i chose mage) and it took me a while to get used to it. After a couple of more I swapped out cards with ones i had and crafted a couple (like the seven mana choose 2 of 4 effect guy).
i also played battlegrounds, but only got through the tutorial one because something was up with my connection to the server or something and i kept dcing from it.
I noticed they changed the rank system and that a lot of cards got unnerfed. Also saw they changed priest, added new portraits, and a new class is coming soon and i looked at some of the cards for demon hunter, and my god
Most of the cards un-nerfed are either no longer in standard or won't be once the new set comes out.
