new champion select qol change

i saw a lot of threads asking for the "fill +except x role" and it really got me thinking why not just let us pick more than 2 roles? i mean let me pick 1 primary and as many secondaries as i like.... will it do any harm? also, you would be able to q faster. in addition it will help all of the people who want to fill but are afraid of getting support all the time. tl dr: instead of 2 roles must be picked: at least 2 roles must be picked
