Why can't we have a check for a player banning your pick if on the same team.

Nothing can boil the blood of a player more than having a champ selected and at the very last minute your teammate bans your champ. IDK what would be the best method to alleviate this frustration, whether keeping track of when your band pick == a pick from your teamates, and getting a toxic chat warning (similar to a queue dodge timer), or If the banne could get the chance to immediately leave. I am sure there are plenty of more ideas how to handle this ( making it so teammates cannot band a pre-picked champ on your team could also work), but it just feels like its a small thing that is in no way being handled currently.
