Can runes be more interesting? They're just micro-optimizations right now.
The same thing that got Masteries reworked, Runes basically just add tiny bits of power to you in uninteresting ways. Oh look, +9 starting armor, joy... Oh that guy went +15 starting AD, how original... Oh that guy took one Quint in flat armor instead of AS... You see where I'm going.
While Runes are very functional, they're very uninteresting. Worst of all is that people have to grind for them; I should know because I've got every Rune and STILL have too much IP left afterwards that I can't spend.
Riot can't be satisfied with this, right? Surely we could get some revamp to the Rune system so that it's more dynamic and strategic rather than just "only one setup works for this Champion"?
