Here’s what I propose in short.
Change tournament days to happen on every day, with each day yielding different rewards…
Monday, Wednesday and Friday yield vouchers. 10k for 1 win, 20k for 2 wins and 35k for 3 wins.
Tuesday, Thursday and Saturday yield Iridium. 75 for 1 win, 150 for 2 wins and 275 for 3 wins.
Sunday yields GS. No change in rewards.
Make all battles go between ranks 8-11 for more dynamic gameplay.
Game mode selection is random. Capture the Beacons excluded.
