not so long ago in western countries ppl tended to be much more "competent" as you call it
its a development from the last few years, where games became less "doom" and more "call of duty" (maybe you know this already, see
https://www.youtube.com/watch?v=C4yIxUOWrtw) and the audiences like it as these games still get bought a lot as it seems
"cattle" ppl are not only showing this mentality in games, in RL you also see this behavior pretty often
just dont become this way yourself...
but see it positive, when you are not a casual player you have lots of easy enemies so its more fun dominating in PVP
PS: do really so many ppl feel offended when you just state the obvious?
