Just hit radiant today, after being in immortal 2/3 in act 2 and most of act 3. Solo Q my way 90% of the game.

One tip I have for players who are in high diamond and low immortal that wants to push for higher ranks - learn to support and use your utility for your team, not just for yourself.

I never Instant lock, usually let people pick what they are comfortable with. That made me learn pretty much every champ in the game except cypher. My last 10 games pretty much consist of KJ and Omen. I one-tricked my way with duelist (Jett and Raze) pretty much all the way to diamond 3 (beta rank). Which then the games becomes so heavily team based/utility base that I started learning other champs to let the aim gods Reyna do their work. My mentality is to do whatever it is to put my team at an advantage - my average kill count in immortal 3 games are probably about 15 per game. Biggest difference with a good team is they use utilities not just for themselves, but for the team - knowing when to flash/smoke for your team, calling out, looking at mini maps constantly to know where your teammates are and how you can help.

You don’t need god aim to do well, play for your team, do whatever you think will help your team win rounds, not what will help you get kills.
