Best reasons to play

The new player experience will be a -lot- better in a few months time.As for ranked... It's fun if you can keep yourself from being stressed out by it. Same goes for normals actually.
There will be bad games, -real- bad games, there will be flaming and toxicity and it is down to you to mute them and carry on. If you can do that and enjoy the game, then it is fantastic and worth every second you put into it. :D
