So the vulchers will just wait until the enemy's wheels lift off the ground before pulling the trigger. The only change I see here would be more people trying to up off a capped field because there is no penalty while on the roll. But what about when people are landing? As soon as the wheels touch down, they're safe? Counts as no death, right? So what if some punk is landing his 163 dead-stick and you kill him on his landing roll? You get nothing and he keeps his perks?
