How do I get back into this game after a long break

you log in queue up and play , go ham mash buttons have fun

thats how

you don't get back in you turn around and run the opposite direction.

the game is in a pretty bad state right now.

I'd Co-Op it. That's what I always do, but I don't think I've gone for quite as long as you have. Co-Op to normals I guess.

After a week of playing, you should be getting the hang of controlling your champions and animations.

Whatever you had, probably isn't as good as it was now compared to then.

As for getting good, you just have to play for experience and have a method at tackling your mistakes so that you can evolve as a player in macro / micro play.

By continuing to not play. Its terrible r/n. Trust.

Play a lot
