improve League of Legends

when you go into a match it's hard when you choose a champion and when you have many of them, it is harder. can you do something about it? perhaps as you choose your own visible Campion's playing at the most, or that it looks as if you check your profile - champions then one can choose (tank) and all tanks appear? may make the technique when joins a game. or just come and erase many of my champions I play almost never with type 77% of them. like the idea of making champions visible after selecting the summoner profile then join a game and only they are visible, but when it's your turn to ban champions will all be seen but when you choose champ just 10 or 20 champions appear if you choose so maybe only 4 :). the ARAM champions are and will always be random
