Flanking giving Advantage is a bad rule - if you really want Flanking,
I have a house rule that if there are already 4 enemies adjacent to a target then the 5th+ attackers have Advantage on their attacks, which covers the rear-attack type situation. It is ok but does not add that much interest in practice. I suspect maybe giving characters advantage on a stealth check to creep up behind target & attack with advantage would work better.
