Actually I'm a secret paladin player because I'm still a relatively new player, and the most cost effective deck out there is secret pally easily. I don't have the cards needed for the "more-think more-win" packs such as Control Warrior or Control Priest, but oh believe me I'd love to try them.
Playing Secret Paladin is a compromise you have to do in order to win games in the current meta against people who spend a lot of cash on this game or play for longer.
Exactly, here's the thing. That's how these f2p games all end up working, and to do more would mean you would have to develop a deck on your own and think your way through an obscure and shifting meta. Nobody does that, so you see tips towards the same deck all the time
