And what experience is it that you have, mind I ask? Personally I began my journey within Cs series in the 2nd beta in 1999. I even played the pre beta version of Cs that was leaked in April that year if I'm not mistaken. Afterwards I've played on semi level for some years, until I swap my game of choice to Battlefield and COD in 2010, where I ended up playing at a professional level.
Came back to CS in 2013 and have played master league faceit since approximately 2015. I have worked as admin for several comunitys such as BrutalCs, Playzeek, ESEA and some Swedish minor sites. I've spent years in the community awhole and regardless if COD nor Battlefield has anything to do with CS I've still played all three of them at a fairly high level, which give me a somewhat clear insight what it is all about. Having said this, I can also clearly see that you are more a "fan boy" talking nonsense than anything else.
