The priority should not be attracting new players, it should be keeping the ones you have so they can attract new players. If a patch comes in with this mega super nerf that removes the cancer that is kassadin from the blind pick queue, how are they going to know about it? They are not, a majority of the playerbase does not read the patch notes and even if I did I doubt they'd consider the implications said patch would have on dominion to make them want to play it.
Want to know what would attract new players? Something they can notice without reading a patch. "Oh Dominion has Ranked now, it must be worth playing" is how new players will be attracted instead of the current "Dominion so bad Riot wont even give it ranked, even TT has ranked". Not giving Dominion ranked under the new system just enforces this notion and will make the "new players" you want be alienated further.
