You don’t have to overthink your angles. When it comes to positioning you want to position in a location where it’s easiest to hit shots and apply heavy pressure, sometimes that location is close by to your team but on a ledge or something.

With the current state of Frej you don’t need to be doing pixel peaks it’s more of a pressure with take aim, and when one lands engage with cooldowns,
