Pick and Bans

So been watching the NA LCS this weekend as a tend to do more or less during the season and during every pick and ban phase the shout casters are always saying who the teams will ban and that they can't ban everyone they need to. So I was wondering if during the next year or so will we ever get another ban for the pick and ban phase making it four bans total. I think especially now that we are getting more and more champions in the league three champions to only ban away doesn't really make an impact in the game at all. I see this is especially true for the LCS because pro's champion pool is so deep that basically if you focus one or two bans against a certain player they have more than enough champions in their pool left to play. I feel like the current three ban limit doesn't really impact the game and give it the strategy element that I think it should with the current amount of bans available. Any feedback from someone at Riot would be appreciated.
