league of legends,the game that was desinged to get you trolled."letting your team ban your champ"

you know in ranked or draft mode,where there is 15 seconds befor your team can start banning?in thoese 15 seconds,players are allowed to pick whatever champ they want so their teamates wont ban them,right?this is proof that rito games want to troll us. point is,stop letting your own team,ban your champs,or atleast punish them for it,last que, i was trying to play jax so i picked him befor my team started banning (so my team would know i was gonna play jax).someone asked for my role,and when i said no, they trolled and banned jax. rito,just remove the posibility of banning a champ if one of your teamates pick him in draft,there is no point in letting your team ban your champ,just remove it you are legit helping trolls.
