Men desire to be the aggressor to much and women desire to be the waiter too much. Going against our natural instincts will help fix a lot of the idiosyncrasies of dating and make for better dating and better relationships.
Women are naturally good at guessing how they will feel around other people and waiting to find the right man based on what they see and feel about them. But men are naturally good at analyzing the mental and physical traits of a woman that would make her a good mate quickly and without much guessing. Women and men can do what the other sex specializes in but most of the time women are built to feel and men are built to analyze.
At a basic level wouldn't you want the individual who is best at knowing how they feel around someone to be the one who asks for a date and the one who knows what they want mentally and physically to do the aggressive flirting and date accepting so that there isn't much guessing once a date is propositioned?
I think that if men learned to patiently wait and women learned to be more aggressive and ask the man out then this would erase most of the idiosyncrasies around dating. Women don't like it when men are too pushy because they know what they want (even though this is what they are built to do) and men don't like it when women take their time to learn what they want (even though this is what they are built to do).
Conclusion: It all comes back to this, men desire to be the aggressor too much and women desire to be the waiter too much. Going against our natural instincts will help fix a lot of the idiosyncrasies of dating because women would be forced to finally make a decision and men would be forced to wait for the women to learn about them and make the decision to ask them out. This will increase the chances of good dates and good relationships.
Note: women will still guess wrong and men will still be pushy even if these roles are reversed so the idiosyncrasies of dating will still exist. I simply think that if the roles where reversed it would decrease the chances for bad dates and bad relationships and increase the chances for good dates and good relationships.
