Event pass milestone missions

With the latest event, Night and Dawn 2019 concluding shortly, I would like to bring up a specific issue I had with this event's milestone reward system. Previously, every milestone was laid out before you, with each just requering you to earn more points. This time around, riot decided to split them into more milestones, making each requiere you to earn 15 points (5 per win, 2 per loss). This change was made, so that we, the players, could get more rewards out of the event pass, but in turn it has made is more frustrating to farm these missions.

It feels extreamly frustrating, "wasting" a win, when I'm on 14/15 points in a specific mission. I've completed all the milestones on two accounts, and not wasting at least a single point when finishing the mission felt like a very rare occourance.

When I bought the pass, I was greeted with "more rewards, less grind" which now feels like "more rewards, more frustrating grind"
