Stop saying "just reduce damage" is the solution to everything.
All mobas thrive on variety. If you can't provide that, the game dies. Of course, Riot thinks variety is the need to introduce some ridiculous new gimmick with every patch to keep the game "fresh," totally oblivious to the fact that their 134 character roster is plenty capable of doing that for them on its own, without them releasing some half assed attempt to reinvent the wheel and risk breaking the game each time. The state of runes reforged at the moment means only a select group of 30 some odd characters can benefit from it to any meaningful degree. Each rune does something SO SPECIFIC, it's obviously going to benefit certain characters far more than others.
Now the disparity between a tier 1 character and a tier 2 is so massive that the tier 2 character has to tremendously outplay the tier 1 player as to be hilariously unfair. Now consider the characters in tier 4 and 5 (or even tier 3, frankly) and ask why anyone in their right mind would want to play it.
All of the game's problems stem from Runes Reforged. In case you forgot what happened in November, I'll remind you:
Runes Reforged is released. Average game's duration shrinks to 20-25 minutes at the exact same time.
Constantly squawking "REDUCE DAMAGE, REDUCE DAMAGE," doesn't solve the underlying problem, it's a bandaid fix at best. It DOES NOT account for the disparity of champions' and their viability in relation to each other.
