Crazy idea, but what if we removed Triumph
Imo this rune is one of the worst offenders for making dumb risky players overly rewarding, and a huge contributor to games snowballing out of control early. I can't count how times I've seen a slightly fed champion just barely win a 1v2 or survive a poorly executed dive because of Triumph.
It also overshadows the other two runes in the vast majority of champions, with Presence of Mind only being used on a small handful of champions and Overheal only being occasionally used on ADCs (with Triumph still being taken twice as often). It would be nice to replace it with something more in line with the other two runes.
