shorasaroseI think the aim you develop in games like these are more suited for MOBA and RTS players honestly
MOBAs need aim? What have I missed?
Being faster even by a few milliseconds in a moba or RTS increases your chances of winning especially if you're consistently faster cause you could build a extremely small lead at the beginning into a much bigger one after 10 minutes or so.
As exc0 pointed out this doesn't transfer 1:1 in game. Usually I recommend using aimbooster or aim400kg to newer players to help them work on their mouse control which I'm a firm believer that good mouse control makes learning to aim in game easier. That being said if you get around 1 minute or higher the 1st time you try this you probably don't need to improve your mouse control unless you find this enjoyable. PR is 2:10
It's also good to quickly test out a mouse to see if you like the way it feels or test out a new monitor or monitor setting.
-edit-
to help show how much a different a monitor can make I've tested
the Dell U2312HM which is a 1080p 8ms panel that I oc'd to 75Hz vs my BenQ XL2420TE which is 1080p 1ms 144Hz and another monitor which was a Dell 1440 x 900 5ms 75Hz panel
Personal Records
Dell: 1:33
BenQ: 2:10
Dell 1440 x 900: 1:41
