Another problem we still have with rune pages
Besides the consistent error message we receive when adjusting runes in champion select, there is another concern that keeps the rune system from feeling polished.
As of now, runes cannot be dragged to order them in a different sequence like the masteries last season. This may be due in part to the new rune system probably being built off of the old one. I do not know if Riot plans to address this specific concern but I would like to express that this change is justifiable for people that want to order their pages on champions, their respective classes, and playstyles.
