I rarely make suggestions, but I have one and I've received positive feedback so here goes:
After experiencing the beginning of this League Tournament I think I have a pretty good grasp on what is going to happen each week. When everyone's league points get reset to 2500, all of the strongest players on the server will start to gain league points at the expense of the weakest players in the SuperHero League because everyone is of an equal value right at the start. We are all at 2500 league points, so why wouldn't I hit someone that I am way stronger than.
What I suggest is that based on where you finish in the League Tournament the week before, your points get reset to a different value. Maybe 51st-100th drop to 2525, 31st-50th drop to 2550, 21st-30th drop to 2575, 11th-20th drop to 2600, 4th-10th drop to 2625, 3rd to 2650, 4th to 2675, 1st to 2700.
I don't care exactly what values, but this way when the week starts there is more benefit to you to hit someone around your strength level that you can beat (so you get more points), rather than the weak ones who are just trying to secure a place in SuperHero League. It may look on the surface like you are giving even more advantage to the strong ones, but if you are strong enough or play a lot, moving up one or two tiers in this new system in a week would be reasonable.
