How to not get mad at Call of Duty?

As most of y'all know out of every good game Call of Duty ended up with the "noobs". COD has alot of good stuff as well as bad. Good:killstreaks,perks (well some of them),good guns etc... Bad:noobtubes,noobs,knife lunging,poor hit detection and much more. I get pissed at the hit detection most of all. I shoot 10 bullets and don't even get a hit marker. I get mad and wanna stop!! I can't stop playing the game because it's so addictive. Don't tell me **** plz.Lol I want suggestions plz. THNX everyone.
