Maybe they could add 5 more reward tiers as rank 1 with stars that would also help to separate PvP matchmaking slightly better too. 5k rating for 1 star, 10k rating for 2 stars, 15k rating for 3 stars, 30k rating for 4 stars, and 50k rating for 5 stars.
These rewards would also help to justify the relatively horrible rewards given for the top 1,000 players, particularly the top 100. The 1,000-101 reward for the PvP leader board is the only reward that is almost balanced for the amount of time it would take, and even that isn’t the greatest. Making rank 1 also include a 5 star system like that would help to consistently reward people regardless of how overly active the community gets. Many players can easily get 5k rating in a week. I am near there this week and around 20,000 players are there at 5k+. Thousands of players could reach the 2 stars at 10k. The other 3 would basically just be a consistent method to buff the rewards for people who play an insane amount making grinding like that to be worth it regardless of position finish.
