The vet system brings too much gameplay and fun to the table to just blatantly remove it. Just so the Setons player can have instead of their -10 air fight, a -7 fight for their ~30 seconds. Not a very good argument against the whole vet, because normally there is not a problem with that.
The vet system is not perfect, but at the moment it is good enough to focus on other problems. cough RAS SACUS cough
Could be the air revamped to produce less spam? Debatable.
