A Suggestion for Riot!

I believe that the ranked system should add a banning system for items! There are plenty of really strong champions right now. For example, is really strong right now. If there was a banning system for items, this could be good for bad for . A Zed player could ban Zhonyas, a known counter to Zed. But, Zed is strong due to lethality. Lethality has a limited number of items that offer it. If the enemy were to ban lethality items, this would make the game more challenging for . This could also be said for other champions as well! I would like you guys in Riot HQ to take this suggestion some thought!
