whats your go to strategy to win ranked matches?

The cheating is so rampant in ranked right now I'd say at least 75% of the players are using those cheat boxes.  Ranked really isn't worth playing right now until they start a ban wave for these people abusing the system.

Notice they all have rapid fire and their guns empty out almost instantly.  Guns like the Prowler and G7 fire automatically instead of their normal shots.  Also, they use illegal movement in console, meaning they are either using illegal key binds or they are MnK players using emulation.

I've played ranked for 4 hours tonight, and not one match do I feel I lost fair and square.  It's rare you fight a team that is not like this.  I think early rookie 4 are the only lobbies that are probably fair right now.
