I totes understand that, but if the only defense for some champs was a tight knit team comp and you’re trying to force said comp in a meta that it doesn’t work in, that’s not adjusting your playstyle to what’s happening.
I’m not really trying to argue bc I’ve seen you on the forums before and really value your thoughts bc you make good points super often! I’m just a bit iffy on this because I’ve found hextech relatively easy to adjust to personally (maybe it’s just at my elo though, which is high gold/low plat depending on how well I can make my brain work on a day to day basis lol).
I haven’t had much issue with spreading and assassins because assassins still aren’t super viable in the handful of games I’ve had opponents run them against me.
Generally when I see multiple opponents running hextech, I change my positioning to counter them as much as possible with a 4 man front line and split carries. Sort of like a sideways [ shape if that makes sense? And it seems to be really effective, even against blademaster/gunslingers. Splitting the items between the carries also helps due to only one of them getting canceled out by hextech and the other still being able to be a carry.
If running guardians you still get the trait bonus on your front line which helps, and can still locket the front line if you run that item. It might not fully solve the problem but it’s the best chance of getting through with minimal losses that I’ve found so far.
