It takes a very long time to build up muscle memory on on mice. Not days, but weeks and maybe months.
Alot of people think OK plug in mouse and keyboard then suddenly they are god.
Ask any PC player in this forum they will all tell you they struggle against PC players in public mode due to high skill ceiling. Go up against a PC player when on console you get wasted anything beyond 20m range.
Some controller players on twitch I've seen can out perform most PC players.
The skill gap is smaller in close combat.
They should just throw console and PC players into same pool for match making, sbmm off and turn off aim assist then let them use whatever control method they want.
PC Players can use whatever control method, they can use any monitor, they can buy any brand of mouse/keyboard. So might as well say some PC players have advantage over other PC players too.
Or say I am a console player, rapid single fire controller with 120" projector and someone's head pixels is size of my hand.
Anyone can afford a PC to play Apex due to low system requirements, like a £100 graphics card even. You're going to need a PC/laptop anyway as can't do your banking and career work on a console. So a PC is multipurpose whereas a console is an appliance.
If anything PC is cheaper as you can access multiple digital stores like Origin, Steam, Ubisoft etc and consoles tied to one digital store and one streaming service. But unfortunately PC cheating has gone too wild now, so make it less appealing.
