I got a question about the new champselect.

First of sorry if this is the wrong place but i didnt really knew where to post this question.

My most played champion is swain even though i only play mid 1 out of 5 games at best. I love the boss bird but i dont like firstpicking him and my only other midlane champ is galio which also isnt something you firstpick. Even though i love these champions i only pick them after i got some information about my own and the enemy their team. Will i still be able to play these in the new championselect of will i just get reported for not playing the role im asigned? Or if i picked support but the enemy picks yi, zed and riven will i still be able to go rammus jugnle?

I like playing support and when im first or second pick ill almost always go support i prefer it if i can be 4th pick and i can pick the champion in the role that the team needs and because i know the match ups i pick those champions in i still can preform really good in those roles without mainning them and get a lot variation and fun in my games.
