You are missing a feature where you can set a priority for the team members when using Round Robin. This is how it should work:
Hubspot would assign the meeting to the team member with the highest priority relative to other available teammates. The priority could be set to each team member.
If team members have equal priority, Hubspot would assign the meeting to the least recently scheduled person for this event type
Agreed this would be a huge help to automate leads to Higher performing sales reps
