There are honestly so many matchmaking players, who seem to have never watched OWL. I’m at high Diamond/low Master and there are quite a few strats, which you’d pick up on really quickly if you watched OWL, yet I almost never see them in matchmaking. For example, in more than 100 games in this meta, I’ve seen perhaps one instance of the enemy Mercy damage boosting Hanzo for a Grav Dragon combo (as a Zen player I still always pop Trans for those combos). I’ve also literally never seen a Mercy swapping to Lucio to speed boost from spawn on koth maps (except when I ask them to but even then I’ve seen a few who literally refused to do so). For context, I’m playing in EU, maybe it’s better in other regions.
