More Poor programming then a bug in champion select
if you click on a role, and after that search for a specific champion, they don't show. Example, you click on Support, and type Garen... No garen appears... Search should always overrule the select type, cause you are going to get less result from the search.
-Situation- When people get filled for a role, they don't know all the champ of this role, so they click en the role to see, if they don't like the champ so they want to choose another one, but can't, cause the search don't work anymore.
