Um difficulty not so much, I think the way they fight on the ground needs to be handeled better
They need more powers at their disposal, they shouldn't suffer from Cotton puff attacks ala THEM swinging at you and you not staggering or being thrown back, I intend to address alot of my grips with them but over all yes they are the sixiests beasts in open world gaming.
I didn't get how a grounded dragon could be so much weaker than a flying one, but then you realize, when they are on the ground, they use their wings for balance, not fighting. Makes sense as the wing membranes are the weakest parts of their body. However, they should be able to rear up and fan you with the wings, like a whirlwind effect, pushing you back. Also, they are not collision'd properly. You can walk into their body at some points, but at others, you can't get close enough to hit them with a dagger. But that's game mechanics.
The dragons are beautiful, very artistically well-done!!! I don't care if I see a hundred maudlin dragon fights, I enjoy every single one just looking at those magnificent creatures! Well-done, Beth!
