Runes Reforged was not a mistake... completely.

Runes Reforged tried to put runes and masteries together in a single 5 option set. That wasn't the mistake.

The mistake was the damage creep that you implied in every single rune, whether that be for tanks (Demolish, Grasp, Aftershock), assassins (Ignite procs Electrocute, impaired bonuses of up to 40% bonus if using the right champion with the right runes), and just all classes in general.

The buffs that all champions got and item changes without compensation nerfs caused this before the season even started.

BUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUT. . . . . . . . . . . I miss my old runes and masteries anyways. So I'm biased anyways.
