step 1. figure out your spacing. simplified thought process i use:
if the enemy team is threatening to flank you, can you hold a position where you can easily monitor and deny the flanks?
if yes → hold farther away and in that position
if no → hold somewhere within range to receive peel from team (varies depending on what heroes can peel for you and where they choose to hold)
if the enemy team is not threatening to flank you, further generally means safer… but it also means you’ll lag behind if your team pushes out of your los.
step 2. find a corner in that position and hug it like it’s your best friend. ideally it’s elevated, near a healthpack, takes a slightly wider angle than your team, and denies line of sight to places dmg is likely to come from
