Honestly, I went straight from intro to blind on accident but I didn’t turn back. It took me a while but after learning that my first ten games (about, at least) in actual PvP would always be unfairly matched (smurfs, people of varying skill and trolls will inevitably cross your path during your first games), I chose to bite the bullet and keep at it. If Co-Op is something that’ll make you feel comfortable, then by all means move through the levels as they become easier for you. But if you’re up to it, it’s never a bad idea just queuing up for the real game - all you need is patience. Your first games are likely to be very different in experience, but eventually the game will find a spot for you where you could actually grow.
