Bring back team builder, or let people sign up for ONE role in new builder.
All day today I've been getting nothing but the secondary role, and almost never once got the actual role I wanted to play.
Team Builder was nice that way, I felt like doing something specific, and other than maybe a long timer to getting into a team there was nothing to stop me from doing that specific thing.
The new builder is an improvement at least, in that if you got bottom pick, there was a 99% chance you were gonna get one role and one role alone regardless of what you actually wanted, usually Support. But now unless you wanna play as a support (to which you're almost guaranteed to get if you put it in Primary or Secondary role) it's a 50 / 50 shot whether or not you get the role you wanted, or the role you're settling for.
TLDR: Let us just sign up for one role in the new champion select, add a "N/A" option beside "Fill" or something.
