First off, I think we all agree that personal preference is the main factor of mouse sensitivity. Doesn't matter what is "ideal" if it doesn't suit you personally (This goes for heroes in overwatch too).
-----------------------------------------------------------
So, I've discussed mouse sensitivity with my brother Ryjeon quite a bit. The subject came up recently with my brother, Ponce, and I as well. Everyone else (aside from me) appears to use a "low sensitivity" (generally speaking, low DPI and Low in game sensitivity). This gives them better control for their aim.
However, I've always played my games with high sensitivity. I'm actually pretty surprised that most pros play with a low sensitivity. I always expected high sensitivity to be the norm when I first started playing games.
My reasoning? Well, I figured your aim will always improve with team. Eventually, you should have enough muscle control and memory that you know exactly how much to move the mouse (with lazer accuracy) to get to your location regardless of sensitivity.
Here is the scenario I originally based my judgement on. Assuming that two players see each other at the same time from the same distance on the screen. Both have immaculate aim, so in this scenario, both are guaranteed to hit their target. Assuming 1 shot 1 kill, who wins? Assuming that they have the same reflexes, the person with high senstivity. Just because the perosn with high sensitivty will move their mouse over the opponent a millisecond faster. I personally feel like this is why I was so good at CS:S when I played. Because I knew exactly where to shoot and I shot first. Of course, I always played like 8 hours on weekdays, and like 16 hours on weekends back then. So I was almost always in top form.
I'm not saying either way is superior. On paper high sensitivity may be superior in a perfect scenario (like the one listed above). Robot vs Robot. But Low sensitivity may actually be realistically superior in actual application since we aren't robots. It could very well be that humans are limited and actually have a higher aim percentage with low senstiivity because of higher precision with their mouse.
The other concern is the physical act of moving the mouse. With high sensitivity you tend to move with your wrist. With low sensitivity, it tends to be your arm. I would say your arm is better in the long run to avoid injury. Which made me worry about my situation...
But I have such high sensitivity that I actually don't move my wrist so much. I noticed that the way I move my mouse is by my thumb and fingers. I basically glide the mouse underneath my hand. So my hand/wrist actually moves very little. This is also why I can't play with a heavy mouse (like my Logitech G700). I have to play with a light mouse because all I am doing is pushing/pulling the mouse with my thumb and basically pinky+ring finger. I'm not saying I never move my wrist, I just don't always move my wrist. Which I think is why I don't have issues personally.
Anyway, just a personal observation I felt like sharing.
