I lost a ranked game because Mountain Dragon sucks.
First dragon was mountain dragon. We got it. "yay?"
But the seconds dragon was botched, and the enemy team got it. Infernal Dragon.
My team never reached a tower to benefit from mountain dragon, in the next 15 minutes.
Eventually, we get in position to take another dragon.
It's another Mountain Dragon.
My jungler, literally won't take it, and walks away. Some of my team, stays, and dies when the enemy team shows up. Then the enemy team pushed directly to my base [they also didn't care about mountain drake], and took the nexus, because of that.
Because of Mountain Dragon.
Mountain dragon is literally not worth 20 gold, unless you already have an advantage in the game. :(
