Do us all a favor and please, take a warm up game
If you are just getting off a few month (or some other extended period of time) hiatus from league, don't hope right into a ranked match. You obviously will be rusty and not at the top of your game, understandably so mind you. Plus you may not know the META. So take a game in Normal Queue to get reacquainted. Maybe even 2 just to be sure before you go into ranked.
