Chamber has a very high pickrate while Yoru has the lowest pickrate. In any case any changes they want to make could break either of the characters too much. So what do you think would make Chamber act more like a "sentinel" than duel...

I’m not a super high rank so I can’t speak for all ranks, but personally silver was unbearable. Between afks, zero comms, etc, I was hard stuck for the longest time. I breezed through gold and am now in plat.
