I'm confused by Riot's logic

"Normal Draft will be retired at the start of preseason for all regions except North America, Europe West, and Brazil. Our goal is to offer the fewest number of queues that give unique experiences (so we can keep queues healthy) while keeping disruption low, and in all regions except NA/EUW/BR, normal draft had very low participation. In an ideal world, we’d like to retire normal draft in all regions."

Why not retire Blind Pick?
