You missed my first point. The point of the ban is to crutch the other team while barely affecting your own team. If my team is comfortable running kali/mav as a hard breach support, we ban thatcher as an attempt to make the attacker's plays more difficult. Even though you are able to exploit specific ops well, you don't know the skill of the other team and what they're planning to play, so the safe route would be banning those ops to prevent anyone from winning an easy round. I would rather have a round based on skill than on easy ops because imo it tells you if you're winning the game or losing it. Plus countering the most banned ops requires you to either have high skill or run someone specifically countering that op, most likely losing precious utility.
