Very disappointed to receive a box full of 3 grey poops when I got 6 star R1.
Maybe new achievements to be introduced:
Reach rank 4: Premium Box
Reach Rank 3: Premium Box
Reach Rank 2: Premium Box
Reach Rank 1: Premium Pack
Reach Rank 1 6 stars: 1000 tokens
Please TS, we work hard at this game, and arena needs more players. This once off incentive will boost arena popularity and cost you nothing.
For players to reach R1, they have most likely already spent money. Learn to be more rewarding to top players at least. The introduction of new achievements is long overdue anyways.
