I really enjoyed the brief talk on stealth device, leverage, and hull. It was very insightful and helped me understand when and why I was right or wrong on a stealth/hull pick.
I am not impressed by defenders. The jousting metrics will not be enough for them to make a deep impact IMO. I love the ships, but I don't expect them dynamically shifting the meta. Now the new bombers on the other hand...
Have you had the chance to test them out? The bombers are great. Defenders are phenomenal.
