So, if youre really just starting the game, i would not play 2v2s unless you find someone else around your skill level to consistently play with. 1v1s are better for learning and testing.
The first several ranked 1v1s you play are really just “calibration” games to put you into an ELO range where your skill level correlates. So if youre new you are probably going to lose for a little while until youre at the right skill range.
My advice: just stick with it. Practice against the AI, play some ranked. Get familiar with the game and youll be addicted.
