Blizzard needs to take a look at adding incentives to play this game.
They have two systems in place:
1. Dailies
2. Ladder
-Dailies. You a pack every 2.5 days. It's pretty slow, but it's a F2P game. I have always thought about it as their indirect way incentivizing you to shell out some $ to speed up the deck gathering process. I have no problem with that. Dailies are probably just fine as is.
-Ladder. An endless treadmill where you get to compare epeen with ananonymouscommunity. How and why am I supposed to care about beating anyone when I have no conceivable way of knowing who they are and cannot even communicate with them. Unless you are one of about 15 streamers in the world, nobody knows and nobody cares who you are or what rank you get. There is no reward for playing 300 games a month. You are not even going to be be "Better" at the game than when you started, in the same way grinding 300 games of Dota, Sc2, or Counter Strike would increase your skill. It really is just an exercise in time allotment and repetition.
My assumption is that they will never have a market place where cards can be traded or sold, nor does it behoove them to just "gif more gold/dust/cards", so there has to be new elements introduced.
Here are a few ideas for rewards which could be earned:
1. Animated hero portraits with cosmetics that your opponents could see. Collecting full cosmetic sets could give your hero a special taunt emote or animation.
2. Weekly Quests: NPC boss fights, where you only get 1 try at beating them.
3. Monthly Quests: They would be more along the lines of "achieve rank 10 on the ladder".
4. More unlockable emotes.
5. Interactive pets that dance around the screen, piss on the plants, and entertain you while your Priest opponents takes max time and drags the game out for 25 minutes. Your pet might randomly attack your opponents pets, or maybe they just might like them and be more friendly.
6. Hot Streaks, where you get rewarded for winning 5+ games in a row.
7. Trophy/Achievement room in your player profile.
8. More collection bonus' like "Old Murk eye". Beasts, Demons, Dragons, Pirates, etc.
9. Unlockable lore entries by playing the cards X number of times.
Other Ideas:
1. Optional chat/facetime with your opponents. Check-box "Yes to Chat", both players must have "yes" check for any chat messages to be displayed. Who wants to compare epeen now?
2. Blind Arena's in Play Mode, where you are matched up against a random opponent with random non-drafted decks... but everyone is assigned an equal number of common, rare, epic and legendaries.
3. High Stakes Mode, where you can bet 500 gold and play an opponent in the best 3 out of 5 match, where winner takes all.
