It does not go back. IMO you have no chance of getting back to 2 before the end of the season. I got a chat restriction a few weeks ago, and since then I only say positive things in chat (good job, nice kill, thanks for leash), and I always honor someone every game (unless my whole team is toxic, lol). I play maybe 7-9 games a day, with more on the weekends. Its been maybe 125-150 games since my restriction ended and my honor is still locked. From what I've heard it is a few months after it gets unlocked (if it even does this season) to go from 1-2. You might be better off creating a new account assuming you can climb the ladder faster than you can recover honor.
