I'm thinking of Dark Harvest, but I think there are a few runes that apply to this topic. (Gathering Storm also)
Games just end to fast.
Dark Harvest REALLY starts to take off at like 35 minutes+ but who cares?
Adjust the runes to ramp up at 25 minutes, cuz lets be honest, 25 minutes, is new late-game.
I'm not complaining. I think 30 minute games are fun.
Just show love to the "late-game" fantasy, because right now, you are way better off just going for the early bully.
In one game, I got dark Harvest to REALLY start ramping up, but it was 45 minutes in, and I was fed like 20 kills....
At that point I could have had any rune, and still carried the team.
The Dark Harvest just felt like a bonus to winning.
