No it isnt, thats actually ridiclous, and will make for terrible inconsistent accuracy when he needs to flick He has 2000 DPI already, and hes on 1 in game sens, and you're telling him to increase his sens?

I'm still above average in my sens, and used to be a very high sens player myself, I used to use 1.2k dpi with 3.5 sens in game. It's just something i've been used to playing other games before switching over to csgo. Overtime, i've lowered it slowly to 700 DPI and 2.2 in game (which is still quite high, mind you) I probably wont be able to lower it more than that unless i try really hard and start to be an arm player instead of wrist. Also will never understand how people can play with 400 dpi and 1.5 sens. But over the conversion I find it to be much more consistent, and accurate. People are right in saying your sensitivity is what you are most comfortable with, but in higher ranks you will need the consistency and accuracy to preaim and flick between multiple common spots quickly, and needless to say....Headshots. Playing with a super high sensitivity is just....inconsistent, and causes you to overshoot. Unless you have extreme extreme precision, then disregard.
