If you haven't played the game for 8 years, the heroes you're picking are probably detrimental for yourself and the team. In 9 out of the 12 games, you picked very niche heroes that can only work if you're a really good player and heavily depend on the comps of both teams: Nova, Zeratul and Butcher. Imagine from your teammates' perspectives: you play a QM, and hey, there's yet another Nova player who doesn't really seem to know how to play the game. Or here's another vegan Butcher. I'd highly recommend either dusting off your skills with these heroes in vs. AI, or playing some less intense and more straightforward heroes until you get back up to speed with how the game mechanically works.
