Dr Yo,
Your example above (augering to improve K/T) would benifit only players like yourself, who have a high K/D, good points, and could afford to drop them in half or more. However, the vast majority of players would be harmed by intentional augering. For an improvement in K/T, they would take a bigger hit in points and K/D.
Then there are a handful of players whao are the exact opposite of you. They have a high K/T, lower K/D and points. They would be wise to land any sortie when they get some kills, and a chance to run home. Landing a four kills would earn them as many points as 16 on a sortie that they died on. They also would improve on K/D, where their rank is also suffering.
After a few sorties, their K/T rank may drop from 100 to 200, but their point rank might go from 2000 to 1500, and their K/D rank may also go from 2000 to 1500.
They would trade a KT rank drop of 100, but gain 1000 on the ther 2! This is a good trade.
This score system promotes a well ballanced playing style.
