This season with new rift I've noticed a terrible error with the dragon buffs.
Dragon buffs are great. It's cool to have objectives with heavier weight in the jungle. But on the opposite side of the same coin, and i'm not so much complaining as i am stating a fact. With the new dragon buffs and changes to baron and the addition of crab. In Solo q ranked if your jungler is bad or doesn't see dragon as an objective? You're screwed unless their jungle thinks the same. Because dragon buff is so strong and people somehow still don't realize it. It puts way too much swing over the game in a single role. I know jungle was basically always one of the more important role. But now it's to the point where if you have a bad jungle, it's over. There's no way to win that game. End of story.
TL:DR Too much weight in the jungle role, dragon buff OP. Bad jungles end games on their own.
