Hey there Bad Ol Putty Tat,
I've actually got some good news for you! Anyone who was below Honor level 2 by the end of the season aren’t able to earn rewards. Cases of cheating and MMR boosting are also stripped of rewards. You can find the announcement here. You can still earn rewards on this account for future seasons, but the same rules will apply.
However, as a one time only for the 2018 season. If you are honor 1 or 0 when the season ends, have only been chat restricted, and have not been cheating or MMR boosting, you have a one time chance to reach honor 2 by February 11, 2019 on the same server you were gold in. If you are able to do so, we will be doing a re-grant of end of season rewards for everyone who reforms.
