I was watching a really great podcast the other day that revolutionized the way I thought. The guy said that you need to do everything you can to set yourself up for success (and defined success as winning wsg), so roll a BM monk. In the same podcast he said the number one most important thing that can be gamebreaking is movement speed. From this I've taken that I need to roll a speed-potting BM monk, because that gives me the best chance to win, and to hell with interesting games. I've also learned from a few games recently that AFKing out means that I haven't actually lost, therefore all I do is win.
Now you might say, dude, that's not going to help you in the premade scene! How will it help you in the premade scene? Jesus Christ, think of the premade scene!
The answer to that is simple, there is no premade scene, because everyone is too busy dick measuring and gaining instagram followers for games to actually happen!
Worst case scenario I dodge, blame my team, or point to my pristine winrate.
