I hope not! Hopefully it has been correctly balanced!
For me this season, I made at 3500 Rshares per win. So the first win brings 4-5 bronze chests and I finish the day with 15-20.
Next season, that 3500 Rshares per win will brings me way less silver chests, but I hope that the quality will make up for the quantity... I hope!
I guess we can only wait and see
