i've lost interest in this game
i don't like being locked into classes
the classes are poorly balanced
very little variety
ccg's will always be pay to win
this game is obviously degenerating in the same way magic did - power keeps creeping up and the game is decided almost immediately
I'm gonna have to disagree with you.
WARNING: Long post incoming
Regarding class balancing, these are the decks I've consistenly won over 50% of my games at around or above rank 5:
priest (multiple deck types)
hunter (face hunter, mid range)
warrior (control without staple legendary cards like rag, alexstrasza, barron geddon, etc)
warlock (both zoo and handlock)
druid (mid range, double combo)
mage (classic, mech, echo, freeze)
rogue (oil)
Even shaman (mech, zoo, murloc)
Most of these decks I use zero legendaries like rogue, shaman, priest, mage. Except maybe loatheb from naxx.
Regarding variety, as mentioned by someone a few posts ago, there's pretty different ways to play each hero. Eg: when facing rogue, it might be mill or oil; mage could be a freeze or fatigue or mech, warlock might be handlock or zoo or demonlock etc, for each hero there are different VIABLE archtypes...
Regarding pay to win... last year when I first started playing, I was overseas for an extended period and so started playing on Europe server, which has remained my main account. On the other hand, I've never spent a dime on the NA server and have a completely free to play collection on it (haven't even bought naxx). I still achive above rank 6-7 on a completely free account on NA. I admit it's harder than if I'm playing on Europe where I have a nearly complete collection but not too much so.
I'm sorry to hear that you've lost interest in hearthstone. Hearthstone is the first game in around 15 years that I've stuck to playing almost daily, even if for only 5 mins a day. I haven't consistently played a game online since the days of games like Red Alert, Warcraft 2, Total Annihilation, Starcraft, Rainbow 6, Warcraft 3, Counter Strike 1.6, Day of Defeat, etc.
