Tell you what, I hadn't played in about a year, reactivated my sub about 10 days ago. I remember all my keybinds, I have my 306, tactical and set bonuses, ready to go. I queue unranked, it's going fine.
Then I decided to queue ranked, first game I get called a bot and I get told to stop queuing. So I'll take that with a grain of salt.
I'll still queue and get better at it over time. I'll just keep the chat closed.
