People say the game is too unstable with updates reworking it and that studying its data is useless. These people are wrong. Why? Because the core concept of items/heroes does not change with small percentage changes (ex. Sprint Boots will always improve speed) and a gamer's play style is unique enough to form patterns tied to winning and losing games. Studying the streamers below is my evidence of this. But you might say that Deadlock is 6v6 and studying a single person isn't right. If buying Spirit Resilience has a 15% win rate for you, you are not good against heroes like this and need improvement in this area, regardless of your teammates. But past games are not accurate to the current state of the game. You are right and I have put a half-life on older matches in relation to the date of the match to correct this. Reviewing the play style and winrate of streamers they will continue to play heros they are good at and this makes sense because they need to put on a show. But this doesn't give feedback on movement. I can only do so much. But this doesn't factor in my aimming. I have plans that I cannot share because the haters will sabotage me.
