[b]I used to play on 10 as seen in this video.[/b] But now I am down to 4, more so because I have recently been playing more pvp which requires more precision with those snipers. But due to the current state of pvp I might just stick with pve, and with that I will probably adjust it until its back to 10. But sometimes I change it depending on which weapons I am using. Take a rocket launcher for example which feels more heavy but if I put the sensitivity up a little, it will feel the same as my primary. At the end of the day people have different playing styles and they require different sensitivity settings. Based from my pvp experience over the years on past pvp games....higher sensitivity is good for rushing and slower is better for camping back and playing more sneaky. I believe that for the win in a team based match, sneaky with low sensitivity and being able to get those precise kills is crucial. But for solo play, rushing and having fun, not so serious...high can be a lot of fun. It all depends on the player, their style, the game mode etc ;) For sneaky play and more serious I would recommend using 3-4 For rushing and fun I recommend higher, you can get good with 10 and it feels a lot more fun. :)
