"in a 5v5, you enter the site with a counter strafe and you either win or lose the aim duel with the player who is holding the site" You are complete garbage. If you don't believe entrying requires talent and GAME SENSE then you are shit at the game and furthermore absolute garbage at entrying.
"in a 1v1, you enter the site depending on the information you have" In your BRAINDEAD scenario the player has NO INFORMATION BECAUSE THERE HAS NEVER BEEN CONTACT. You basically enter the site until you find the 1v1 situation in which a duel HAS to occur, unlike in 5v5 situations where a player can be utilized without even firing a single bullet, you braindead piece of shit.
"he is holding based on the information you have, like
-who he is
-who you are and what he knows about you
-and most importantly, what has happened previously in the round" That already happens in normal play you fucktard. It's called watching fucking demos, it's just that in normal play you have 5 times the homework to do for 5 times the players.
"why are you strawmaning me and talking about 1v1 tournaments? unable to make any good arguements without talking about 1v1 maps? you're making this very easy for me ;)" Get fucking destroyed you lazy piece of shit. If you believe that less players are better then start your own tournaments and connoisseur in your dream to rebuild this game that has been shaped in over 20 years, if you believe you can do a better job than pros and devs have done for 2 decades. Completely retarded, two words to best describe you. Now fuck off.
