i feel like the meta is built around the fact that anythign that is too easily countered isnt viable. if the enemy wasnt hardcountering your picks though, they might be very vulnerable, to a very hard hitting class cannon spire for example, where in a game where any seriously specialized ship can be specially countered.
the ships we see now, especially in the competitive scene, are heavy control ships designed to counter reactive ship builds like the junker or galleon. if you couldnt be sure what the enemy was bringing, then you couldnt be sure that your very specialized control mobula would be appropriate, so you might brign somethign more rounded. you might also decide that a risk would be fun, adn fly a ship that is so absurdly topheavy in some respect that anyone with 5 seconds could counter it easily if they brought the right build, but agains't anything else was very powerful (im looking at you hellhound/mine-spire....) Galleons, spires and junkers more generally have very little showing in competitive scene because its too easy to shred them at long range, but there would be some trepidation before bringing a control mobula if you couldnt be SURE no hwacha fish or disable squids were going to come ruin your day.
another point id like to make is that both sides would be equally blind, so balance wouldn't be any kind of issue, except that players that win a lot due to hard counter-picking might not win as much, and that is perfectly alright with me....
