Having everyone start together in Bronze is a failed experiment, at least in my region. Getting Plat+ to pop is as rare as hens teeth.
What hasn't helped was the glitch where a good number of the players who got to Plat first who play a lot just carried on getting into gold/silver lobbies to progress past Plat, through Diamond and into Apex Pred. Means that anyone who didn't know about the glitch or didn't want to use it are now sat in a queue of 18 players waiting for Plat games to pop for 10 minutes to only then have to go back and play regular Apex.
They should reset ranked and seed the brackets up to Diamond by some of the S1 results they collected so games actually start popping. It's not a perfect solution but it's better than people just not even bothering to queue for ranked anymore because they can't get a game.
