You don’t make any sense. How is 0 information and 6 players scrambling to instalock DPS better than a couple people instantly being known as tank/support/flex and reducing the RNG to 4? What I currently find is tanks and supports not instalocking and waiting to see what the DPS do before picking, which factually wastes time.
People are going to pick what they are going to pick, and knowing or not knowing data is not going to change that. At least knowing role preference will aid the players who care to win make their choices faster. You sound like someone who gets tilted based upon a single person asking you a question pre-match, lmao. God forbid people seeking to win games try and communicate with you and damage your fragile snowflake ego.
