It's better to make a bad play with confidence and make yourself as hard as possible to punish, than to make a good play nervously
They still play the same way, but they're so used to playing this way that it's difficult for international teams to counter them. They've done the same plays thousands of times already and they never thought to change their strat instead of perfecting the bad plays
That's the result of being isolated, and cut-off from the rest of the scene, for so long.
It's like, yes from a macro perspective the plays are bad, and there is a theoretical way to punish it, but when it comes to using those theoretical punishes, the international teams don't have as much experience punishing them as FPX have experience perfecting the micro of those plays--because no scrim partner in any other region ever does those plays lol
