Riot should do more with Runes to encourage interesting gameplay, not just kills
With runes reforged, we got lots of cool runes that stack up rewards. The problem is, most of these runes ONLY stack when you get kills.
Why don't the stacking runes work off of tower kills, or epic monster kills?
I understand CS not being a good stat to allow them to stack, because that would encourage uninteractive laning, but at the very least give people some equal motivation so that towers and epic monsters are weighed at least a little bit against kills!
Edit: Somebody brought up the example of Eyeball collector. This does stack with ward kills, but it's not exactly accessible to everyone like the kill stacking ones are. Kill stacking runes are present in multiple rune trees, while the ward related ones are only present in Domination.
