The problem with DFA is that you have to divide the damage inflicted into two parts - the damage caused by physical impact and the damage caused by jumpjet exhaust. If you barely make it up over your opponent's head and axe the jets, then you'll gently plop down on their shoulders. That's not a kill! You'd just make gentle contact, lose your balance, and promptly fall over onto your face/back of your head.
If DFA was implemented properly, you'd have to put some height into your drop to make the impact more substantial, which will cause some amount of leg damage to you, or you'd have to fire up your jets right as you land in order to torch their cockpit.
I am all-for the JumpJet welding technique.
