I dont know where you are getting vulching kills, its extremely rare for anyone to up when a base is being attacked as it is, let alone lost.
To be the leader on the board takes a month worth of killing, not a lucky vulch day...but even then, if you are vulching you put in the work to deack the whole base and manned guns. I havent seen a good vulching in many years.
If you are too timid you might get a decent K/D, but kills will come slow.
I love when people try to HO me, saves alot of time. Yesterday I upped while being horded and a 190 dove straight down at me to HO and bit the dust. Wasted all that altitude and E on a long flight just to try to kill me first. Gave me a chance to take a good plane out of the fight and kill all his buddies much easier. Of course he raged on 200 and logged.
