This brawling system is unbalanced. I was attacked 42 times within 2 hours and I attacked once. I also have heard that once your DEF drops below 0 that you can still be attacked, but you now have less DEF to protect yourself against their attack? The way I think it should work is that, once your DEF hits 0, you can't be attacked anymore, until it recharges. And I think it would be more balanced to have your DEF take away as much DEF points that your pirates are worth that you have on your DEF crew. Like, if I have 107 DEF points, and my pirates add up to 102 DEF points, then when I get attacked, take away 102 DEF points, and make it so that I cannot attack, or be attacked, until my DEF has recharged. I don't know if this is a good idea or not, but give me some criticism.  

Even so... It's not that far fetched from when there wasn't the GvG event. The higher levels (Most active players) practically have a bounty above their heads because of the bonus Brawl points for winning against them. It doesn't take much to win a brawl. Those who beat me, I can easily get revenge. All I'm saying is that it's unbalanced.
