A possible rework of hero bans in pubs?

I wanted the community's thoughts on a possible rework of the ban system in pubs. Currently it bans heroes based on a combination of win rate and pick rate, as far as I know. A common complaint I see brought up is that people really want to just ban specific heroes that they hate playing against.

How would you guys feel about a pre-determined ban list per player, something along the lines of pre-selecting 3-5 heroes that you want banned and when the match is made, the matchmaker takes into account the ban list from all matched players, prioritizing heroes that appear more often in the players ban lists and ensuring that they are banned.

This is definitely more work for the players but it could result in better match made games as heroes who appear more frequently on the ban list of the 10 players are more likely to be banned.

This is a pretty rough idea so I understand if people don't quite agree but I'm open to suggestions and discussions, personally, I don't really care for the current ban system as it never bans what I want and always bans the hero that I've been itching to play for the last week.
