Hearthpwn

Hi, I played WoW with a free starter trial from a CD a couple years and I want to play it again for Lady Liadrin in Hearthstone, but when I go to the battle.net client to play, it says:

"Subscription expired. Click to setup subscription."

Do you have any idea as to what I should do about that? This is my first thread so if this has been mentioned before I'm sorry. But anyway, I'm reinstalling the game so I can't try to get in the client yet so maybe I'll be able to figure it out eventually but if you have any idea as to what this means please let me know. Thank you for reading. 

Reasons I hate playing Hearthstone right now in the current meta: 

1. Control Priest uses the damn deathlord to buff to an ungoldy number with Valen's Choosen, Word, anything. I'm playing decks like Reno Hunter or Malygos Druid where I have to draw a silence or I'm pretty much fucked the whole game trying to get rid of the fucking card. Not to mention the amount of removal that Priest has, it's almost as much Warrior altough they completly STEAL your shit which pisses me off more. Goddamnit Entomb just annoys the shit out of me, yeah I need to bait it out but if I'm playing a Control mirror, they just stole one of my best cards. 

2. Secret Paladin. Not much is needed to say here. I've been playing against this bullshit ever since the Grand Tournament.... FUCK THAT SHIT! I can't even explain how shity the meta became for the sake of Paladins. They are so hair tearing to play against, I gave up laddering in Hearthstone just because of that class. 

3. Druid FON + SR = BLIZZARD NERF IT NOW! 

Good day, I'm ready to give up and try hs again in 2 months well played.

yeah, this brawl was supposed to be fun, i enjoyed on the first day but, people dont understand that whem they're supposed to build  deck, they're supposed to build a deck of they on. they come to this very site, netdeck the top rateds and keep ruining the brawl

I second that dude, I swear every time I try the brawl it's just tempo mage, tempo mage, tempo mage and tempo mage again. 

I'm sorry to say but I hate mages so much, wether it's tempo or mech I hate it. The only type that'I kinda like is freeze. Scorers Apprentice, Flamewaker, frostbolt, I fucking hate watching my board die and their board develop with such obnoxious cards like those. Don't get me started with the mechwarper.... were the FUCK is standard when i need it???
