Where the A-20 excels is in the ability to pound the snot out of armor, and then wade right into a dogfight. Usually, if you are defending against a horde of tanks, you are frequently evading enemy fighters. That suits me, I can usually force a ping-free overshoot and get some hits in. Tonight, I managed to get 10 tanks (6 Panzers, 4 Wirbels), and 2 fighters with several assists on other fighters. Didn't take a single ping in exchange.
The A-20 is a very dangerous adversary for armor, and good enough air to air to defend itself against marauding fighters looking to pick while you're dealing with tanks.
I enjoy the A-20 because its adaptable, competent (if not especially good) air to air and simply fun.
