Comeback mechanic is broken with ticket bleeding.

So I was in a game today where we held 5 objectives out of 6 from the beginning for over 5 mins and the ticket was 1100 vs about 900 which is somewhat normal but then the enemy regained ground and they controlled 4 objective and in like 2 minutes our ticket went down by like 600. This does not really seem fair because when we had that their ticket barely moved.
