Suggestion About Ban&Pick in Rank

Hi, there,

I had a problem these days while i was in rank:During the Ban&Pick Phase, it happens often, that my team accidentally ban the champ i wanna pick :( Although I've already declared my champ , but somehow someone in my team hadn't seen it.

So I came up with an suggestion: Could Riot make it possible, that during the Ban&Pick, the team can't ban the champs , which are declared by the teammates?

Can anyone from Riot see this(I hope so xd )?Or I might as well write another Email to Riot?

Thx for reading if anyone read this and wish all of u good night xd.
