No, you’re not the target market, the Target Market spends money. The target market is the group of players that keep the game alive. Those who constantly post and whine and complain are not the target market. While there may be at times some good suggestions from F2P players, those who complain are usually players who feel a sense of entitlement that they don’t have.
And you clearly did not read the post properly.
No one is forced to buy anything. You can still climb to legend as a F2P Player. 80% of cars in an expansion are useless. This illusion that you need to have all these cards to climb is simply not true.
Your statement about it being pay to win is also not true. Is it more challenging? Yes, but it’s not impossible to get legend as a f2p player. I became friends with someone on hearthstone discord and helped them put together a hunter deck from the cards they had and crafted a few I suggested. He didn’t put any money into the game and hit legend.
It’s all about your attitude and state of mind. So if you limit yourself and blame everything but your skill, you’ll never hit legend.
