because hardscoping is really easy so noobs do it and quickscoping is harder so better people do it
Actually CoD is one of the least skill-requiring games ever, you fail on that and the fact that professionalgamers don't really quickscope....
Until you become an actual professional that quickscopes the majority of his shots then you really don't have much backup for your common and stupid claims. Quickscoping is easy, I had about 100% accuracy with it the first day I tried it, and I have more trouble hardscoping on games that matter (Battlefield).
Furthermore, there is already a thread on CoD that has been sticky'd. Suggest you go there for discussions on this game (because imo, CoD's are the same game <3 ).
