Which league are you in?
This is from the ranked matchmaking details:LOSS FORGIVENESS
Similar to the Elite queue, there will be loss forgiveness in Ranked. Loss forgiveness is defined as zeroing out any potential losses in RP for a match. For example, in a Diamond match where you came in last place but had two kills, you would normally have a -2 adjustment to your RP (-4 from the Platinum entry cost, +2 for kills, for a net loss of -2). With loss forgiveness, however, you would have a net loss adjusted to 0. However, this will only apply if you stand to lose RP from the match – if you had five kills and loss forgiveness, your RP would still be net +1.
We will grant players loss forgiveness when their matchmade teammates abandon the game, and for other cases where we determine you are not to blame for leaving a game e.g. client errors. We plan to be more lenient at the start of the Series but will be vigilant in monitoring player behavior. We will become stricter about granting loss forgiveness if we detect it is being abused.
