There is nothing cheesy about decks that win the way they are built. Wallet Warrior for example requires a lot more dust to build (or money) to accomplish the same in a longer time period, especially at the start of a ladder you want to go quickly through the "less skilled" people to compete with the real meta that starts around rank 10. But even then, aggro decks are more popular because they are quick. You either win or lose usually between turn 5-8, if your win% is around 55% you will climb much faster than for example a slow Handlock or Control Warrior, even if your win chance is higher since your games take twice or even more time to finish.
People also need to understand that ladder rank meta is different than legend rank meta. If you play control warrior on rank 20, I am sorry you are doing it wrong IF you want to rank up. If you just play for fun, obviously it doesn't matter but might as well just play unranked. So, don't complain about people playing the correct deck for the present meta.
Usually my way of ranking up was go retard zoo/hunter until around rank 5, watch the meta and switch accordingly.
Btw, the only reason these decks are looked down upon, is simply the fact they are cheap to make and work. So, everyone can play them = even retards can win with it, that's the logic behind the reasoning. (lol) If everyone could afford to create control warrior (around 10k dust I believe) people would say: "oh man, I run into so many of them, and they actually win that means even retards can play them". You still need to play correctly to win vs. mirror matches or bad match ups. Obviously vs. decks that your deck is designed to counter you don't need a brain to play it. But that goes for relatively all decks. Shaman > Handlock for example, don't need to play that "good" to win that match-up.
Deck knowledge based on pre-GvG but these are really the basics that count in any HS environment.
