I mean, those aggro decks still have to win. Is it quicker to play an aggro deck? Sure. I don't think that means they're worse players/decks necessarily, however. I don't know how else you'd make a ranking system though. Do you make longer games more valuable? That may result in people intentionally delaying the game, even when they have lethal. That would be even more frustrating than losing to an aggro deck and moving on.
What I think really hurts and pushes people to aggro decks is the low cost of entry for them, vs. a high cost for control decks. Blizz really need to release effective control cards at low rarity in order to help push that archetype back into favour. But control cards also tend to be the most "interesting" cards, which means they will likely make them rare/epic/legendaries so people will buy more packs.

I dont mind the Aggro decks winning, I mind beeing forced into playing them due to the ranking system beeing all about grinding x amount of games in a set timeframe.
I want a ranking system that shows a players skill and not just that he has played x amount of hours more then someone else.
Right now almost anybody can reach legend given enough free time to play the game, thus it doesnt reflect true skill until you reach legend and have to grind that latter.
I also see zero reason for legend players beeing forced to rank up each season from low ranks.
The Fifa system puts people in different ranks. Then in order to rank up you need to win x amount of games out of a set amount of games. And the ranks never reset.
That means once the ranks settle you end up at a rank that truly reflects your skill.
It also means that legend players only have to play legend players, unless they loose x amount of games and drop rank.
You need to play lets say 10 or 20 matches each new "season" and win a set amount of those matches in order to maintain your rank.
Suddenly people will be thinking alot more about what kind of decks they are playing and not just go for the fastest deck that lets them play a ton of games in the quickest timeframe.
