So 2H has way more untechable time now*. I think 2S and 2H might have gone up a level each (making 2H the new "Level 6" instead of 6H?).
* the OS could've teched late, but in a previous match, Potemkin lands 5K > 2S > 2H > Hammerfall Brake, f.S > Heat on another Potemkin, which I can't recreate in AC. So I'm assuming that wasn't a late tech.
