If you don't have 300hz+ monitor, a 300 dollar mouse and 30-50 ping, you can't win any games at all. If you have low ping you get diffed, oh your a unfortunate man who can't afford high end specs?? DIFFED. sad world
You can make it to Immortal 3 with 50-60ms ping.
You can make it to Ascendant on 60hz.
You can make it to Plat with a shitty mouse.
You can make it to Diamond with 60 fps.
Literally none of that shit matters if you have a dedicated 5-person squad or maybe a trio. Having any teammates makes the game 10x easier and gives you so much edge over the one solo queuing guy on the other team.
