Yet another "Can we bind rune/mastery sets to champions"?
Alright Riot, its time to complement all those 'options' and 'strategic diversity' you've been talking about with a mechanism that allows us to make some of these decisions, one of which being, to setup non-mandatory, opt-in custom bindings feature.
I envision everything working the same as it currently does, with the addition of a bindings tab in the profile next to the itemsets tab. These optional bindings will set for defaults (what the drop-down list boxes start off as when a champion is selected). They can of course still be manipulated during the champion select screen.
The current behavior, as it seems to me, is the settings default to my previous match (regardless of champion).
