14,947 Kills 8,687 Deaths = 1.72 K/D Ratio at Level 36. Your stats are 9,839 Kills 6,782 Deaths = 1.45 K/D Ratio at Level 31. You have some catching up to do :-) It's achevable. Using the Classic Controller Pro isn't as difficult as some people make it out to be. I have a 2:1 kill ratio about 70% of every match I play so my Kills are rising faster than my Deaths. I am hoping to get to a 2.00 K/D ratio.
You mention Hip Firing not very easy with the CCP. It can be if you're not using the proper gun for the job. I own hip fire with the Vargen and Stuager and also all the Shotguns, every other gun is a bit worse as I dont like to hip fire as much with anything else. Once the speed of my horizontal turning using ADS is matched with the speed of the enemy is running i'll hip fire, but if I can ADS faster than what the enemy is moving ill stick with ADS. It comes down to what feels comfortable and I have my controls at what I feel is to be perfect setup. Thats also a big performance aspect is how your controls are set up and what you can get use to with out it being to fast or slow.
You really cant get advice from anyone else unless they are using the CCP themselves cause I can put myself in your shoes and until I found a set up someone posted online my controls were kind of sluggish, but at that time I thought they were good. Once I changed them to what the guy had his at it took me a few matches to get used to it but once I did I will never changed them again.
Playing styles depends on the person if you are a hide and seek or up in your face run and gun player.... I am run and gun/melee guy. Catch enemies off guard and plow them with bullets or smack them with my gun lol. When you run and gun hip shot is the way to do it. I suggest using the vargen for that. When you have people camping in their usual camping grounds, I'll fly in around a corner and bomb/spray the hell out of the room with my Vargen.
Honestly it's the little thing's that can make you a better player, I have a few thing's I can brush up on some too. Practice makes perfect.... For most people.
