Change the Howling Peak Arena (Dragon boss arena) Shape

The fight in Howling Peak has had many complaints, and I do personally think it is one of the worst boss fight experiences I've had in a game. Which is sad because it is very close to being a good challenge. The change that would resolve many problems with the fight is to fill in the donut shape of the design.

Because of the open hole in the middle you have less area to maneuver for dodging when the dragon is stunned and falls, or is attacking with its death laser. This difficulty of maneuverability is in addition to the snow which already hampers your abilities. While keeping in mind the arena is always a part of a fight with bosses in games, the current arena design makes it too strong of a foe you have to pay attention to in addition to the powerful moveset of the fell wyvern.

From my personal experience fighting it, I think filling in the arena's central hole would alleviate many of the frustration points of the fight by giving the player less impending falling doom to worry over, so they can focus more on fighting powerful dragon, and more area they can use to dodge the various attacks.
