New rank system (EUW)

So from reading Riot's content I already figured out that in EUW they are gonna be keeping track of both the old and new rank system (with the new one not showing). However, something bugs me about that regarding playing in your off-role. For example, I am better at mid (let's say Gold 1 than I am at Adc (let's say Silver 2). So quite obviously I am a higher rank in mid. If I am Gold 1 in the EUW rank system, due to playing mid, and I pick Adc to play in my next game, will or will I not be placed with Silver 2 MMR? TL;DC My question is: Even though we cannot see positional ranks, will still be matched as if we could? Because that would indirectly give some feedback from EUW at the same time.
