Here's what Runes Reforged should not have been:

MoAr DmGzZZZZZZZZZzz Here's what it should have been: Create meaningful choices and new playstyle based on those choices.

The Inspiration tree, for one, is an absolutely great example of what Runes should be. Some others have great concepts too - such as Predator, Press the Attack, Aery's defensive component or even Conqueror. But why does everything need damage forced down its throat? Why force damage into Press the Attack (having increased damage from all sources after a met requirement makes sense. Just frontloading it with damage doesn't); or Aery's damage (which was inevitably nerfed again and again), and why does Conqueror need 1.2k gold worth of AD in lategame???

Runes should be more utility focused rather than simply another damage overload. Some are admittedly in a good spot, while others need a major overhaul or simply removal, if they bring nothing but MOAR DAMAGE to the table.
