An issue with the deck slots idea is that it needs to be aesthetically designed in a way that a second page would be intuitive regardless of skill level. But if tavern brawl from 2 weeks ago is any indication, most players don't really pay any attention to ANYTHING but face.
If it can be of any help to anyone, I use the Hearthstone Deck Tracker,
which, aside from allowing you to add a good deal of useful info to the Hearthsone interface, pretty much solves the 9 deck slot problem, since you can save decks within the program and it has a scipt to export them.
@EnragedFilia: And here's me, still not even having all of the basic cards for half the decks because i only play like once a month. I don't even understand what most people are talking about when it comes to Hearthstone. (and my horrible w/l rate shows it off >.> )
@Zacsi: I don't know. With zoolock I can manage a pretty good winrate against secret paladin. The only aggressive decks that I tend to have trouble with (from memory, not statistics) are mechmage and zoolock better than mine. Slower opponents (handlock, control warrior) are much harder to deal with.
And ofcourse the biggest problem with these decks is the only way to reliably win is to SPECIFICALLY build your deck around them. So everyone just plays them to get ladder. I don't fault them for it but Blizzard really just needs to put the hammer down more often on the on op shit like this.
I don't really run into a lot of facehunters nowadays. The most played are: Rampdruid, since FoN+SR is still the "you instantly lost as soon as I draw it" combo.
Patron is still viable since now they have even more draw from not needing warsong.
And ofcourse LoLadins that just vomit secrets at you
Blizzard deck slots was a complaint since beta and cannot be too hard to implement, just make a second page! You have like 7 inventory tabs in diablo, you have a ton in wow I bet, but you cant give the card game more deck slots? Fuck you.
@Guamo Luna: Yup, they're 700 per wing if you pay in gold. It's dang nice since not everyone wants to pay RL money for digital stuff (especially when it comes to like $20-25 for one adventure in the form of digital cards). Just finished Naxx finally via this route last week.
Regarding deck slots... Has the deck area always had a slider bar? It can display all nine at once, but has a blank unusable slot below them.
Maybe they're planning to add more slots as a buyable feature?
@ArteAlen: I have most branches of all 3 adventures because I save my gold from all the daily quests to get them. Takes about 2 weeks per branch though.
