I definitely feel that way. The game is much more enjoyable after you achieve 12 wins in arena and Legend. I do think the ranking system is really flawed though. In most other games with rankings there is more of a safety net. In Hearthstone you can get to the next rank and lose 2 games and get demoted... it is very discouraging.
Think of popular games with competitive rankings like Starcraft 2 and League of Legends. If players just got promoted to masters or diamond, then immediately got demoted for losing 2 games there would be outrage.
