If Riot wanted runes to be more thoughtful, why are Aery and Comet so boring and uninspired?
There is actually no thinking involved between the two at all. It's basically I cast a spell and my keystone does damage, I'll take whatever keystone does the most damage on this patch.
There is no "Oh maybe I shouldn't take this in this particular match up because I'm playing this type of champion" or "Oh maybe I should take this because most of my spells are single target" or "Maybe I want to have a little more sustain damage instead"
It's simply boils down to "Oh Aery is OP for this one patch so let's all just take it into every match up no matter what type of champion I play or damage I do" then when Aery gets nerfed we're just gonna see everyone taking comet instead because it also has no thinking or playstyle involved besides just generically casting spells.
At least in a tree like Resolve I have to think "Maybe I should take take Aftershock because I want to engage quickly using my control abilities" or "I'd rather have extra healing and on hit damage during sustain skirmishes" or "I'm playing support so guardian might really help my lane." There is also a lot more thinking involved in Precision, Inspiration, and Domination to.
