Champion role priority after multiple secondary role placements.

Was just wondering if there shouldn't be a system in place in the new champ select that gives you priority for you "primary" role after say 2 or 3 games on your "secondary". During the 4 games of my ranked placement games i took jungle as primary and adc as secondary, and played 4 straight games of ADC before the champ select was reverted to old style. I won every one of them so that's not my boggle, but i sorta do wish i'd get at least one game of jungle xD. Especially in placements when everyone and their mother are calling jungle (because youtube tells them that's best to carry placements and low elo with), even though half of them don't know how to play it :b
