Not only Pafos, we were surprised by all the matches today when all the home teams lost even though we expected them to draw lol. Tomorrow we still have 3 more matches so will all the home teams lose again? honestly, I'm hesitant to bet on 1x2 especially at this stage. Each team will play the second leg and there is still a chance to turn things around so far we cannot confirm which teams will qualify but for teams that have won by an aggregate of 2 goals yeah at least it's closer.
This isn't that surprising because the teams aren't performing as expected, and even playing at home doesn't give them a better chance of winning. The second leg will be away, so a draw should be quite advantageous for the home team. I rarely bet on these types of matches because they're very difficult to predict, and it's better not to take any bets if we can't analyze them. Anything can happen, but as you said, the team that wins by a 2-goal aggregate has a better chance of advancing.
