i just think it is not good game mechanism for E-sports in general because of unfrequencity and game impact (deflect happen often and you count on them - chance that zis will pen panther is almost the same as that panther will kill is2 , hovewer abanonement chance is so low you cannot even count it or you will never make a move).
But think of it like this. You're gambling already that the panther will not miss the IS2. You're gambling that it will pen the IS2. That's already two variables that have a healthy chance of ruining your day. In comparison, abandonment is actually pretty rare.
Even if abandon didn't exist, it'd still be a risky maneuver with no safety net. So why do it without one? There are plenty of tools to make abandonment a non-issue and allow you to safely destroy, or even CAPTURE the abandoned vehicle.
I just think that every time something gets abandoned and it becomes game changing, it was because someone made a mistake. I really enjoy the mechanic, both when I get the opportunity to steal a vehicle or when my opponent manages to steal one of mine. (because I know I deserved it)
Having it be a rare thing makes it a surprise. Suddenly everyone is scrambling to capture/destroy this vehicle! It's fun to see someone run off with it. Everyone gets a little disappointed when it just gets destroyed rather than stolen.
