I'm testing my two account, the first is a gold that finished gold 3 and the other finished silver 1, so gold chests for one and silver for the other.
Currently both have ended up in silver. My gold is at Silver 1 and by Silver at Silver 2.
Keen to see how the rewards vs. Chest volume pay off. Currently at 50% ecr for both and I have 7 Silver chest and 4 gold. Interested to see how this shifts as we settle into Silver 1 and Gold 3 ;)
Stay tuned
