There are a few areas you can look at to improve your play!

Individual Performance:

Watch a few replays of your games and look for obvious areas of improvement. How’s your cs per wave? You play a lot of Vayne, so how well are you positioning yourself in lane? Are you constantly being harassed by anyone with range (which is basically everyone who’s ranged)? How strong is your ward game? Are you buying a pink every time you go back to ensure some area near your lane is protected? Take some time to objectively look at how your laning phase goes, where your weaknesses and strengths are. Then try to keep some of those in mind as you lane, perhaps leaving open a word doc on a second monitor with things to do or a sticky note on your monitor.

Duo Performance:

Are there supports you do well with in lane and some you don’t do so hot with? You could be great with Nami, and rather crappy with Thresh (Yeah, we all know Thresh is always good. It’s just an example). Working around your support’s play pattern and selection can also help influence the style you have to play in lane. And don’t forget, you can always ask in champion select if they’re good at a certain champ that you find you work best with.

Team Performance:

As for team performance, how do you approach team fights/how does your team approach them? Is it typical yolo queue and Vayne is left to fight the darkness alone while the rest of your team dives their back line? Does your team create a tight defensive ball that leaves your Vayne overheating by the protective shell they’ve formed around her? Is someone always over extended or pushing without vision? Take some time to look at the big sweeping things your team does and how objectives are played. Perhaps you can figure out better times to play for baron or dragon and when to defensively ward.

Bonus Comment: Avoiding Tilt

Tilt happens in many ways. A support who constantly takes cs or a kill, a fail flash over a wall, getting crit several times in a row by someone with 10% crit chance. One of the biggest things to focus on is your fortitude. Win streaks, loss streaks, having to play off your main, an enemy living with 10 hp, all can help make you think an impulsive risky play is the proper one every time. Also, when I lose two games in a row, I take a few minutes to grab a snack or get a drink, browse Reddit. I learned long ago to not keep playing on a losing streak after my college rule of ‘never end on a loss’ meant me and my roomie started at 9 PM and ended at 5 AM…Find a way to curb playing on tilt and you’ll go far.
