Riot, have you considered...
... allowing us to choose a single rune path, instead of two in the new system?
One of things I miss the most from the old mastery system, was the option to put all our mastery points into a single tree, which gave us massive offense/defense/utility power while sacrificing the other two.
My question is if that would be possible to replicate with the new runes reforged. For example, instead of getting a secondary path, we could choose to get 2 extra runes from our primary path.
Thoughts?
