sorry for long rant post
its not exactly rocket science. on mirage vs VP, i remember several rounds where olof goes running out for example to peek A ramp while there are a couple guys right behind him who are not peeking at the same time to get the trades. if olof just communicate "im going to run out in front of smoke pls flash me in and double peek" then they get a 2v1 on a player holding close to ramp. but that doesnt happen and he dies in 1v1 while peeking the corner alone. they also have a big lack of practiced smoke executes. basically their game plan is to feed a couple players in at random times and then hope Niko can get a 3 kill. arguably that is also up to Niko being IGL because historically when he is IGL in any team this is what happens, he calls strats where he can bait his teammates to boost his stats while they lose.
game is also pretty T sided at this point, in MM if we can get 6 rounds on CT on mirage, cache, dust2, i believe we have already won the game because you will get 9 on T quite easily with this economy. you can literally buy every round, at least armor + scout or galil and some flashes and smokes. if you get the bomb down, you can buy ak or sg every round.
if the CT side wins the pistol, you eco round 2 and you get SG's on round 3 when CTs have scouts, smgs and maybe 2-3 M4s. if you got the bomb down and lose pistol, you can force buy smgs scout galil on 5 players or 2 guys drop AK/SG for their teammate and play deagle. if you win the pistol, CT have to do one eco and have a weak buy on round 3 without helmets and full grenades, or they have to do a shitty force with $1900 on round 2 and can have a full buy in round 4.
the ONLY way CT can actually get ahead in eco, before round 4, is by losing the pistol and then winning with the force buy on round 2.
instead of worrying about CT side imo faze should just fix their teamwork on T side, have a solid setup. pretend they play darkest dungeon. there has to be a guy in front who is the best at tanking and evading damage. for faze this can be anyone except niko or cold. the second guy out has to be Niko, all he needs is a teammate in front of him to bait and he can tap for headshots on enemies who are engaging that other player. Cold has to be in the back every round, getting escorted into position where he can post up and press mouse 1 when enemies shift walk into his crosshair just like on SK. when they get this down, they can start to fix their smoke executes and anti ecos. focus on trading out kills together, not leaving any holes to exploit.
also they need to stop fucking rushing B or playing slow mid on anti eco vs pistols on mirage, like they are gold nova mm players, its so fucking annoying to watch. just throw smokes A, molotov the hiding spots, flash out, and hold down W with 5 players until you have site control. even if enemies stack A every eco its still safer than taking risk of going mid or B and taking close range isolated 1v1 fights. this was common knowledge in 2016. ppl just got lazy.
