Idea for the 3v3 Ranked

I've been thinking about how the 3v3 ranked game mode has no role select, which is weird considering even Nexus Blitz has role selection even though there are only 2 possible roles. Considering the whole overhaul to ranked this preseason I think Riot should add that type of role selection to the 3v3 ranked queue too. It is really sad that that game mode is so overlooked and that it might end up like Dominion, completely removed from the game.
