I have enjoyed playing defender wings, I find them almost unkillable, with veteran wing leader. Anyway, I played against them and realized, I didn't have a plan. In a timed game you can avoid them. but if you have a huge ship then that will not be able to avoid them and they will be able to destroy it. To be fair they are a lot of points, 230ish but I feel they can handle 300 no problem.
How do you deal with them?
