Thank you for the positive feedback, and Great question!
We did not distinguish between Silver and Gold when searching for matches this time. Since they were selected randomly between 1400 - 2200, which mainly covers Silver, we expect mostly silver matches.
I realize that the level cap of the summoners are different between the leagues, and therefore that monsters may have a different value. We will keep them separate in future posts. That said, I expect the effect to be small on the bar heights here. Thanks for the remark :)
