Dark Harvest.
Remove this from the game, it was less toxic before, and you actually had to earn your stack so when it was 40+ minutes it is was justified for the damage it did.
Decisions like this make me want to quit - and I really enjoy league.
When a mechanic like this comes out I feel disheartened almost every game.
I enjoy the rune system but things like this are ridiculous, this is the FIRST time I've ever complained about a mechanic Riot, sure there are "OP" things in this game periodically but new DH just feels oppressive and sucks the fun out of the game. Almost half of my games are now attributed to "Mid got fed and has DH so its gg" On BOTH sides. Even if I win and they surrender at 15 minutes its just boring and doesn't feel rewarding at all.... If Dark Harvest remains the way it is I - and a lot of other people who play this game - are seriously just going to leave.
