In their current form, rank up gems such as those awarded for completing chapters or acts in Variant content, are not super intuitive. You click the gem and it says "Rank Up Champions" and you think to yourself: "Sweet! Let's go rank up some champions from this list." So you click "Rank up Champions."

You are dropped at the character menu. Now, I have to fish through all of my characters and try to figure out which ones the gem applies to.

Can't you guys have the gem auto filter the champion list for applicable characters? This seems like something that should have been included when these were rolled out. The current process is tedious and cumbersome.
Quality of life, folks!
