@Angwil I know there's a limit to how many points you can lose each day, but I didn't know if this also applied to how many times you visually see wins/losses for your defense.. If so, this might explain why you aren't seeing any after a certain time
@fordesman A single paragon defense is ridiculously easy to counter once you know it. It is a cheap trick used to catch unsuspecting players, but once you identify it then it is a free win. Rae in your team should remove the buff, but you can bring in any lowly built champion with a buff remover or crowd control and end the fight pretty quickly.
One other thing that I do want to mention is that I want to make sure you aren't underestimating the value of Accuracy on champions. I know it is likely that you have intentionally built your Rae champion without accuracy to focus on damage, as I assume she is your nuker, and this is fine. In general though, accuracy is one of the most important stats after speed for any champion in the game, because if you cannot land your debuffs then there's no point in having that champion in the battle
