PS4 NA Vivec campaign this weekend was... interesting.
Several times I saw ballista and trebs blowing right through doors as if they weren't there, and rams that won't turn and hit the doors, even though the doors are clearly up and at 100% health. Keeps include Arrius, BRK. Also seen at Sej outpost. No matter what you throw at the front door, you do no damage.
So now when trying to siege a keep you can either hit the front door with zero effect, or try and take down walls with 725 HP, no small undertaking especially if you're not running in 24-player groups. Makes dethroning or crowning an emp near-impossible since taking one keep has become a chore. I won't even go into how many repair kits you have to spam to fix that 725 HP wall... lol
