Well, I'll bite. It has p2w features. You can throw money to progress better deck construction much faster than buying through gold. Time gating is a P2W feature (seriously don't be so dense about it).
Having said that, this is by far the least expensive CCG I have ever experienced. MTG, YuGiOh, VS System (god I miss that) are far more expensive to even play the game. Cheap decks that are viable to reach legendary exist. The gold grinding rate is fair IMO and the game rewards those who do well in arena. There is little need to to buy packs/arena runs unless you are impatient.
Summary: Hearthstones F2P system works.
