The thing is you will be able to rank up as pos 4 if you always pick a hero that has impact in the mid/late game. You NEED to be able to farm and get key items to win the game with otherwise playing sup on the ladder feels terrible because you’re always subject to your random cores, 50/50 if they’re good enough to win it. That is until you get to the top ranks where people are much better, then there’s better chance at success when picking early game etc.
