Games are so quick that I can't complete Project quests
Currently I am stuck on kill 2 Barons and win a game after earning 12k gold.
Getting even one Baron requires a game of at least 20 minutes. At that point the game is already stomped and the losing team surrenders.
As for the other quest, it's hard for a support like me to earn 12k gold in such short games.
I have tried playing a non-support in normal matchmade games, but I end up losing since I am not as good in the other roles when I need to play against Diamonds and Plats as Silver (matchmaking seems to have some problems). I have also tried bot games (edit: also known as Coop vs. AI), but they are just as quick, so even as a non-support I cannot do these quests.
Any ideas how I could complete those two quests?
