Banning 4 champ's instead of 3

I think that, with the current system, you've got a lot of champs that are 'made' for ranked. Take the current Malzahar as an example, and maybe even lulu.

Over the years, a lot of these new champ's made it to the spotlights (New Taric, Ekko, Kindred, Kalista), together with the picks who were already amazing.

I feel like ranked nowadays is simply picking the best possible champ you can easily carry your team with (Malphite, Yi etc.), without focussing on your actual skill.

This is why I think we should be given more banning options, in this way I think ranked will be a lot more fun and a lot more challenging, since all the 'OP picks' are (mostly) gone.

Please, feel free to discuss down below

PS: If anyone knows, please let me know how many bans you could do in season 1/2/3 and how many champs there were at that time.
