It’s always been useful in figuring out if you need to lead or trail a target more in a shooter, but all these modern shooters have taken that bit out of the scoreboard.
Checking out The Finals and for the first few games, I thought it used projectiles for the guns because I hit more often shooting ahead of moving targets, only to find they are indeed hitscan and hit better when actually looking directly at the dude when nobody is lagging.
It’s the kind of thing you just learn over time as you play. It can be pretty brutal early on tho.
It could be worse- first MOBA I really got into was Smite and there’s ~130 characters in that game.
