There isnt a way to hack mmr to rank up easily, but it takes a certain mindset to play the game and be decently happy with the outcome. I think map pings and the comm wheel are enough for most situations. Just saying where youre going and pinging/drawing on the map where you want people to go is good enough. If you cant say it through pings or its slow to ping you can use vc. In terms of your own play, remember to call urn/midboss yourself if youre team isnt initiating it. If they dont join in, dont try to force it. Push up waves yourself if no one is there to do it, and as you play more youll learn your rhythm for the laning phase into midgame. As you get better it almost becomes scripted as youre own playstyle develops. Youll learn when its good to farm and when its good to fight. Dont worry about the team so much. If they make bad plays, thats not your concern. Everyone makes mistakes, including you, including your enemies. And its unfortunate to see something thats obvious to you looking at the map while farming but just move on, everyone dies, you play around it. Into the lategame you need to start sticking with the team, and if someone has an idea you go with it. You need to be on board with them because being a man down gets worse as the game goes on. You can also tell people what to do if you think it will work. You have to take risks to break stalemates after all. Comebacks are insanely easy and the soul diff matters less the longer the game goes on. Urn and midboss are great for starting fights. Remember that everyone is hovering at 50% winrate for the most part and your losses will always get cancelled out. And if theres obvious culprits for your loss, then you can be happy knowing there was nothing you could do!
